Erosion of Trump's unilateral military authority; Republican party fracturing on war powers with moderates (Collins, Murkowski) and libertarians (Paul) joining Democrats; Congress reasserting constitutional war powers oversight; potential weakening of US executive flexibility in Iran policy.
Similar to 1973 War Powers Resolution passed over Nixon veto, reasserting Congressional authority after executive overreach; reflects recurring constitutional tension between presidential war-making and legislative oversight.

Reduced geopolitical risk could lower energy prices and inflation expectations. However, defense sector contraction may impact employment in defense-dependent regions. Consumer confidence may improve with reduced military escalation uncertainty.
