Until 1968 the US had a completely batshit insane standing order to launch a full scale nuclear attack on the USSR and China in response to a conventional attack on the USA, even if the attack was an accident, and even if the USSR and China were not responsible for it.
Then we have JFK, who was prepared to start WWIII over a tiff in Cuba, Eisenhower who threatened nukes over Korea, and Reagan, who thought it was hilarious to joke about signing a law to bomb Russia.
And let's not forget Dick Cheney, who wanted to nuke Iraq, a decade before 9/11.
I dunno, maybe nuking people is less of a big deal for some American leaders, having already done it twice.
