#6月3日，美國眾議院以215票對208票通過戰爭權力決議，要求川普停止對伊朗軍事行動，未經國會授權不得繼續作戰。4名共和黨議員與民主黨共同投下贊成票，係2月開戰以來首次。雖決議象徵意�� The June 3 vote in the United States House of Representatives carries major political and geopolitical significance because it represents the first substantial institutional pushback against expanded military operations involving Donald Trump and Iran since hostilities escalated earlier in the year. The 215–208 result demonstrates that concerns over executive war powers are no longer confined to partisan opposition, especially after several Republican lawmakers broke ranks to support the resolution.

Although war powers resolutions often face enforcement limitations, the symbolic impact is powerful. Financial markets, energy traders, and global allies interpret congressional resistance as a signal that prolonged military escalation may encounter growing domestic constraints. This can influence oil prices, defense sector sentiment, diplomatic negotiations, and broader investor confidence.

The vote also highlights deep constitutional tensions between presidential military authority and congressional oversight during modern conflicts. Historically, such divisions emerge when wars become politically costly or strategically uncertain.

However, the narrow margin reveals that Washington remains deeply polarized. Even if military operations continue temporarily, increasing bipartisan scrutiny could pressure future strategy, reduce escalation momentum, and reshape America’s geopolitical posture in the Middle East.
