Did the US make any preparations for war before abducting Maduro from Venezuela or before getting into a war with Iran that cost them freedom of passage in the Strait of Hormuz?

Right up until Russia invaded Ukraine, Russia maintained that, no, that troop buildup wasn't meant as an invasion force, and a good chunk of the world believed Russia because it was a moronic idea to invade Ukraine. Trump is far more moronic and power drunk than Putin, and would perhaps not even organize troops befre invading Canada, all because somebody in the inner circle goaded Trump into it.
