The US maintaining order (and providing foreign aid) is a form of soft power which this administration doesn't seem to value (or maybe even understand). It also benefits US corporations and their interests' abroad.
Fairly clear we wouldn't have allowed anyone else to do that.
It's our fault for being the only ones to take defense spending seriously? We just reopened the shipping lanes clogged by the Houthis, which literally the entire world profited from. That could have been done by anyone else but wasn't, because they happily benefit from US interventionism but then pretend to hate it too. You can't have it both ways.
