U.S. Senate rejects resolution to limit Trump's war powers on Iran.

The United States Senate narrowly rejected, by a 50-49 vote, a resolution that would have required President Donald Trump to end the war in Iran or seek congressional authorization to continue it. The vote, which took place on Friday, largely fell along partisan lines, with only four Republican senators joining Democrats in support of the measure.

The resolution is widely seen as symbolic, as the Trump administration has not altered its policy in response to previous similar votes. The vote comes two days after Trump, in a speech at the United Nations, threatened that he could "obliterate the Islamic Republic." Democrats view these votes as a way to pressure Republicans on a conflict that has become unpopular: only 34% of respondents in a recent poll approve of the attacks on Iran.

The war between the United States and Iran began on February 28 this year, with American and Israeli forces starting to bomb Iran. The U.S. Constitution stipulates that only Congress, not the president, can declare war. For months, Democrats have argued that Trump may have dragged the country into a prolonged conflict without a clear strategy and without the necessary legislative consent.

Since February, the Senate has examined resolutions on war powers against Iran 14 times, voting in favor on only two occasions. The House has also held six votes, with three outcomes favoring an end to the conflict. However, even when a resolution passed in both chambers, the White House ignored the result. The growing unpopularity of the conflict, highlighted by polls, is now pushing some Republicans, especially those running for re-election in November, to distance themselves from Trump's position and call for a swift end to the war.
