Harry Truman?
“Harry Truman?”
Technically, you’re right, but his nukes were mild compared to the firebombing we did during WW2 (something that we, sadly, had to do).
Today it’s different, as we’re taking FAR HIGHER yields, as in at least 10,000 times of what was dropped on Japan (when totaled up). Back then, it was busting up cities, now it’s busting up planets, or at least the human presence on such.
