US law is something US citizens get to decide. If they think it's "batshit", they should vote accordingly. In this case sanctions seem a pretty good alternative to going to war.

The US is an oligarchy. Voting in the US is completely irrelevant to which laws pass - there have been studies about this.

It's clear that those who voted recently for the President are getting what they wanted. Voting made a radical difference, even if the outcome isn't one I like. Whatever "studies" you read are obvious nonsense.
