This is a pretty good summary of the worst Secretary of Defense the nation has ever had.
Now, there were - ironically, not ironically - a number of Secretaries of War back in the 19th century were pretty terrible. William Belknap was among the most corrupt people who were hangers on of the Grant presidency. He quit before he was impeached, but the House impeached him anyway. The Senate fell short, because of course it fucking did.
William Eustis and John Armstrong over saw the absolute military shambles that was the War of 1812. Eustis quit in the first months and Armstrong quit after Washington DC was burned to the ground.
So, that's the company Hegseth is keeping.
The difference is that the 19th century Secretary of War was largely unimportant unless there was an actual war going on, which was fairly infrequently back then. They pretty much killed Indians and distributed some patronage. Hegseth sits astride a colossal organization with trillions of dollars in resources and he's managed to murder some small boat operators in the Caribbean and mire the US and the world in a pointless, drawn out, expensive and perhaps economically ruinous war with Iran. In response to his manifest incompetence, he's laser focused on rooting out beards among the troops and doing pushups.
Among the central truths of Trump 2.0 is how the government has been turned over to toxic internet fuckwads who should not be given authority over the carpool schedule.
FWIW, if the House had remained in session, I think Hegseth gets impeached, and I think there's a decent chance he gets removed by the Senate as Republicans try to save their hides before the midterms. With Speaker Moses sending everyone home, there is no way for Republicans running for re-election to distance themselves from this absolute dumpster fire, because it might enrage the collapsing narcissist who gorges himself on social media trolling and culture war grievances.
