Because it sure looked to me like they renamed the department and immediately started bombing fishing boats, then affirmatively decided to start a war with Iran, all while the guy who came up with the new name goes on TV and screams about how we're free to kill more people now.
It’s plainly not an attempt at honesty. Watching almost any speech by Hegseth makes it clear it’s another “tough guy” thing—his latest effort included announcing “no quarter” in the war with Iran, which one supposes he did because it sounds tough, but it’s so incredibly illegal that just issuing that instruction, as he did, even if nothing happens afterward, is specifically illegal.
It’s a modern outgrowth of the conservative belief that we lost Vietnam because we didn’t war crime hard enough (this is a real, and common, thing, talk to republicans old enough and you’ll encounter it often) and that the military’s too soft.
