Summary

  • Attorney Nicolas Sansone argued Sunday that President Trump’s redesign of the planned 250-foot Washington arch into a “Military Complex/Triumphal Arch” constitutes a “belated” effort to “manufacture a national security justification” that does not cure the project’s “fundamental illegality,” because Congress has not authorized the construction.
  • Rep. Don Beyer, a Virginia Democrat whose district includes Arlington National Cemetery, posted Sunday that Trump “wants to set up a pretext to argue that the arch is tied to national security,” and added that operating drones near Reagan Washington National Airport would be “dangerous and impractical.”
  • The principled-negotiation framework developed by Roger Fisher and William Ury, applied here as an analytical lens rather than as a prescription for a process that may not occur, characterizes the conduct on both sides of the dispute as positional rather than interest-based; Chris Voss’s tactical-emphasis framework similarly identifies the trajectory as positional bargaining rather than interests-based negotiation.
  • The opposing coalition’s BATNA spans courts, congressional instruments (including Beyer’s introduced bill, whose procedural status past introduction is not reported), and public-opinion mobilization — three tracks that do not depend on the same facts or the same timelines.

The legal contest over President Trump’s planned 250-foot Washington arch crystallized Sunday, September 21 around the question of congressional authorization. Attorney Nicolas Sansone, who represents litigants suing to halt the project, told reporters that the president’s “belated efforts to manufacture a national security justification for this project do nothing to cure its fundamental illegality,” because, as Sansone stated, “Congress has not authorized the arch and unless and until Congress does so, the project should not be permitted to move forward.” Rep. Don Beyer, who has introduced legislation to block the arch’s construction, posted on social media that Trump “clearly expects to lose a lawsuit and therefore wants to set up a pretext to argue that the arch is tied to national security.” Trump announced the redesign Saturday on social media, writing that he had agreed at the “strong request” of the military to convert the planned arch “into a top grade Military Complex/Triumphal Arch, to house, store, and have the rapid ability to use large numbers of drones, plus Snipers, on both the roof and plaza areas, and additionally have and hold large quantities of sniper ammunition in storage.” The principled-negotiation framework developed by Fisher and Ury, applied here as an analytical lens rather than as a prescription for a process that may not occur, characterizes the conduct on both sides of the dispute as positional rather than interest-based; Voss’s tactical-emphasis framework identifies the trajectory as positional bargaining rather than interests-based negotiation. The available reporting does not document any executive outreach to the litigants, and Beyer’s communication is being conducted through social-media posts rather than through channels addressed to executive counterparts. The dispute is being waged in court and in public opinion, not across a negotiating table.

Interests on the record

The Fisher-Ury framework directs analysts to surface the interests behind stated positions, on the theory that positions are what parties announce and interests are what they actually need. Applied to the article’s reported conduct, the interests discernible on the public record are partial: the available reporting names attorney Sansone but does not identify the plaintiff or plaintiffs in the underlying lawsuit, which limits what can be claimed about the litigants’ institutional standing beyond their legal counsel’s stated position.

Litigants. Sansone’s stated position — that construction should halt until Congress authorizes the project — appears to serve an institutional interest in enforcing the constitutional requirement that Congress authorize certain federal construction, an associated interest in preserving separation-of-powers limits on executive action, and, per the article’s reference to preservationist criticism of the broader construction initiative, an interest in the integrity of historic-preservation review of Washington’s prominent landmarks. Sansone’s invocation of congressional authorization as the operative legal constraint is the most concrete articulation of an interest in the available record.

Trump. The president’s interests are harder to read from the article alone. If the Saturday redesign is treated at face value, it serves an operational interest in proximity of drone and sniper capacity to the chosen site and an executive interest in establishing a basis on which construction can proceed without specific congressional authorization. Whether the redesign was driven primarily by military need or primarily by legal strategy cannot be confirmed from the available reporting; the article does not establish either motive. Separately, the article’s characterization of Trump’s effort to “remake the nation’s capital” — reflected across the White House ballroom, the Lincoln Memorial Reflecting Pool renovation, the East Potomac Park golf redevelopment, and the Kennedy Center naming initiative — suggests, without establishing, a legacy-construction interest beyond what any single source explicitly states.

Beyer. Beyer’s reported position combines the institutional interest in congressional authorization with a political interest in mobilizing opposition to a high-profile presidential initiative. He layers on a separate operational critique: that drone activity so close to Reagan Washington National Airport would be “dangerous and impractical.” The article does not establish how Beyer’s operational critique was sourced — whether from aviation regulators, military doctrine, or his own assessment.

Congress. Where engaged, Congress’s interest lies in preserving its appropriations and authorization prerogatives. Beyer’s introduced bill to block the arch’s construction operates as a procedural assertion of congressional authority. The article establishes only that the bill has been introduced; its procedural status past introduction is not reported.

Preservationists. As referenced in the article, preservationists’ interest centers on the integrity of historic-preservation review of Washington’s most prominent landmarks — the arch, the Lincoln Memorial Reflecting Pool, and adjacent sites encompassed by the broader construction initiative.

Options for mutual gain

The principled-negotiation framework emphasizes the generation of options for mutual gain before parties commit to positions. The option set identifiable on the available record is narrow, in part because the parties have signaled through their positions that the other side’s core objective is illegitimate — a posture that, under Fisher-Ury analysis, shrinks the room for integrative moves.

Identifiable options include a scaled monument that does not raise the security-redesign question, located on a site where authorization is clearer — a move that partially serves the presidential interest in a legacy marker while removing the specific pretext the litigants are challenging, though it still faces the underlying authorization question and the preservationist objection noted in the article. A congressionally authorized structure of a different design, possibly with a security function genuinely requested by the military and sited away from Reagan Washington National Airport, would serve the institutional interest in authorization and could serve an operational military interest; whether it satisfies the presidential interest in a 250-foot triumphal arch is uncertain. Suspension of construction pending litigation, with a stipulated record on the military-request question, would serve the litigants’ interest in a definitive legal answer but would not serve the presidential interest in momentum. A non-monument commemorative element paired with a separately authorized military facility at a different site would separate the legacy marker from the operational requirement, allowing each to clear its own authorization track; it would not deliver the unified monument Trump announced. A congressionally authorized structure on non-contested federal property outside the National Mall would sidestep the specific authorization question raised by the current site while shifting the visual and symbolic location. An interim architectural competition with explicit authorization milestones that tie the project to congressional action at defined decision points would preserve presidential momentum but satisfy the institutional interest in authorization only with a willing executive counterpart. Congressional authorization sought on negotiated terms incorporating preservation, security, and design inputs could convert a contested executive action into a legislated project. A redesign that addresses specific operational objections about drones near the airport while preserving the arch concept is another route. Trades of location, scale, or program against authorization speed are possible.

The narrowness of the option set reflects the structure of the dispute: when parties have signaled through their positions that the other side’s core objective is illegitimate, the room for an integrative move shrinks. None of the options above resolves the underlying authorization question on terms acceptable to both sides without further information — notably, confirmation of the military-request premise underlying the redesign.

BATNA inventory

The Fisher-Ury framework directs negotiators to identify their Best Alternative to a Negotiated Agreement before committing to a position. Applied to the reported dispute, each side’s BATNA on the public record is partial.

Litigants. The opposing side has three distinct instruments on different thresholds. Courts offer continuation through appeal and further judicial review on the authorization standard. Congress offers appropriations power (which can defund the project), oversight power, and authorizing legislation — Beyer’s introduced bill is one such instrument, though its procedural status past introduction is not reported. Public opinion offers mobilization, which can shift the political pressure on both litigation and legislation. The three instruments do not depend on the same facts or the same timelines; the rhetorical position may outrun the deployed instruments, meaning the counterparty’s BATNA may be weaker than its stated position suggests, but not necessarily weak overall.

Trump. If the lawsuit succeeds or congressional authorization is withheld, the article allows one to infer the following alternatives: invoking security authorities to proceed, redesigning further to address specific objections, downsizing the project, or abandoning it. The article does not establish that the administration has publicly named its BATNA. The Saturday security redesign appears to function as one element of a BATNA — preserving the option of a security-based legal theory while the political fight continues.

Counterparty coalition. If the litigants and Beyer’s introduced legislation are treated as parts of one opposing coalition, the coalition’s BATNA is the sum of the instruments identified above, not a single track. The article does not establish that any of those instruments is currently deployed at a scale that would change the project’s trajectory. The opposing coalition’s BATNA may therefore be stronger than any single deployed instrument suggests, but slower than its rhetorical position implies.

Objective criteria and frame audit

The dispute is unusually well-served by objective criteria because the central question — whether the arch may be built without congressional authorization — is a question of law rather than preference. Sansone’s invocation of congressional authorization operates as a documented objective criterion: the absence of authorization is the defect Sansone identifies as “fundamental.” The article also references historic-preservation review and the operational environment near Reagan Washington National Airport.

Beyer’s “pretext” framing implicates administrative-law review of agency rationale. Courts have at times applied such review to distinguish genuine agency reasoning from post-hoc rationalization, though the specific doctrine and its applicability to a monument-construction decision are not established in the available reporting. Applicable aviation-proximity regulation, where it would govern drone activity near Reagan National, is not specified in the article; whether such regulation supplies an objective criterion depends on rules the article does not establish. The same applies to military operational doctrine invoked through Trump’s “strong request of the military” reference: the article does not specify which doctrine or which military request. Precedent on prior Washington construction projects is similarly not canvassed in the article. These are criteria a court is likely to apply; they are not the criteria a negotiation would apply.

The framings documented in the article are reported as conduct — statements, social-media posts, redesign announcements — rather than as motive attribution. The available record does not establish whether the redesign was driven primarily by military need or primarily by legal strategy. The dispute is being conducted on positions rather than interests, and on legal terrain rather than across a negotiating table. The objective criterion of congressional authorization is the standard both sides appear to accept, which means the outcome is most likely determined by litigation and political process rather than by negotiated agreement.

Verifiable-fact inventory

Five specific facts would change the analysis materially if confirmed. First, confirmation that the military in fact requested the redesign — through a Department of Defense statement, congressional testimony, or official correspondence; in the absence of such confirmation, the security framing reads as a legal-BATNA move rather than an operational one. Second, a specific FAA determination or drone-siting analysis on the proposed arch location. Third, the current procedural status of Beyer’s introduced bill. Fourth, identification of the plaintiff or plaintiffs in the underlying lawsuit; the article names attorney Sansone but does not identify a plaintiff. Fifth, the administration’s own statement of its legal theory for executive construction beyond the redesign announcement.

Where these facts are confirmed, an option exists; where they are not, the dispute defaults to its legal track. Engagement conditions include an independently verified military request describing an operational need that could be met by a different site or design, an FAA siting analysis confirming the proposed site is operationally viable (or an alternative site that would be), and a congressional authorization pathway that satisfies the institutional interest within a defined timeline.

Additional considerations

The dispute is part of a broader reported pattern: Trump’s effort to “remake the nation’s capital” through multiple construction initiatives, including a White House ballroom, the Lincoln Memorial Reflecting Pool renovation, the East Potomac Park golf redevelopment, and the push to add his name to the John F. Kennedy Center for the Performing Arts. The initiatives “have drawn criticism from preservationists and others who argue they would alter some of Washington’s most prominent historic landmarks,” the article reports. The redesign announced Saturday would make the arch the second major construction project Trump has sought to justify on national security grounds, per the article’s reporting — the first such justification is referenced but not specified in detail within the available text.

Trump was scheduled to meet New York City Mayor Zohran Mamdani later Sunday at Gracie Mansion, according to Anna Bahr, Mamdani’s communications director; Trump also refused Sunday to say whether he would attempt to demolish the Kennedy Center and announced Saturday that he would appoint an artificial intelligence czar and create an “AI Force,” providing almost no details about either plan. China’s leader Xi Jinping was confirmed Sunday to visit the United States this week for talks with Trump, and a U.S. Immigration and Customs Enforcement officer shot and wounded a man Sunday afternoon in Austin, Texas. These developments fall outside the arch dispute itself but situate it within the same Sunday news cycle.
