That was certainly the 1930s logic regarding Japan. Sorry, but when nuclear weapons are involved you don’t wait to “take the first punch”. That’s something all civilized countries understand. You do not make nuclear threats. That’s crossing a line that will not be tolerated.
Japan had an actual fighting force, and we had nothing compared to today
Japan and the powers that aligned with them were a real threat.
Fatboy Kim is an insect and could be crushed within 24 hours if we really wanted to.
And if he fired off a nuke... we’d really want to.
