The United States has faced recurring strategic challenges in 2025-2026, including earlier action against Chinese surveillance camera makers like Hikvision and Dahua compared to India, ongoing debate over Israeli military operations and US-Israel relations, inherited wars that prove difficult to end despite presidential transitions, efforts to link security and economic reforms in Iraq, and evolving imperial strategies involving NATO rearmament and potential reductions in US military assets for Europe.

For: War wore down America, forcing a deal

• Analysts argued that the United States went to war triumphant and will likely leave greatly weakened. The characterization of the US entering triumphant but leaving weakened directly demonstrates the exhaustion mechanism that this hypothesis identifies as decisive. 1 source, unnamed sources
• Jonathan Lemire and other analysts contend that the war left the United States diminished militarily, strategically, economically, and morally. Analysts directly characterizing the war's impact as military, strategic, economic, and moral diminishment strongly supports the core exhaustion mechanism of this hypothesis. 1 source, analysis

For: Global power shifts made a deal necessary

• The recurring trend in America's Iran policy is more indicative of structural realities of power in the contemporary international system rather than Iran alone. Attribution of policy to structural power realities rather than Iran-specific factors directly supports that structural shifts, not acute war exhaustion, made the deal necessary. 1 source, editorial
• U.S. policy has linked security, economic, and governance matters for years, viewing security environment reform as a necessary gateway to addressing financial imbalances, attracting investment, and alleviating economic pressures facing Baghdad. Evidence that US policy links security and economics to address financial imbalances shows the structural constraints and competitive pressures that drive the deal. 1 source, editorial

For: War and power shifts worked together

• Analysts argued that the United States went to war triumphant and will likely leave greatly weakened. The arc from triumphant entry to weakened exit confirms that exhaustion and vulnerability both accumulated, supporting the mutual-reinforcement mechanism. 1 source, unnamed sources
• Jonathan Lemire and other analysts contend that the war left the United States diminished militarily, strategically, economically, and morally. Direct evidence of war-induced military, strategic, economic, and moral diminishment confirms the exhaustion component integral to this mutual-reinforcement hypothesis. 1 source, analysis
• The recurring trend in America's Iran policy is more indicative of structural realities of power in the contemporary international system rather than Iran alone. Attribution of policy to structural power trends directly supports the structural-shift component within this hypothesis's two-pathway mechanism. 1 source, editorial

For: US politics will kill the deal despite a stable ceasefire

• American presidents inherit wars they did not start, recognize they cannot be won on the promised terms, yet lack the political space to end them, so they postpone the reckoning and hand the burden to their successor. The pattern of presidents inheriting unwinnable conflicts and postponing resolution directly supports the hypothesis that US politics will block the deal despite ceasefire success. 1 source, analysis
• The stability of the diplomatic agreement will depend heavily on acceptance by domestic political circles, particularly in the United States. The proposition directly states the deal's stability depends on US political acceptance, which is precisely what this hypothesis predicts will fail. 1 source, analysis

For: A stable ceasefire will hold the deal together in US politics

No strong supporting evidence

For: The deal becomes permanent US political football with no resolution

• American presidents inherit wars they did not start, recognize they cannot be won on the promised terms, yet lack the political space to end them, so they postpone the reckoning and hand the burden to their successor. Presidents postponing rather than resolving inherited conflicts directly supports the permanent-football hypothesis over decisive collapse or acceptance. 1 source, analysis
• The stability of the diplomatic agreement will depend heavily on acceptance by domestic political circles, particularly in the United States. The deal becoming a perpetual political football directly matches the hypothesis that it will persist without secure resolution, transcending empirical performance. 1 source, analysis
