The significance here is less the stated position than the source: congressional leaders committing to a war's termination is a signal about the political constraints the administration will face, not a policy change in itself.

Whether rhetoric from the legislature translates into binding action is the open question, and that gap is where the difference between a headline and a repricing sits.
