Letter: Trump's atomic restraint in Iran war is no safe bet

Prediction markets aren't taking bets on Donald Trump nuking Iran, claiming public backlash. If they did, their bet would likely be Trump nukes Iran after the midterms; he has nothing to lose. Ironically, I'm visiting near Hiroshima 81 years after Harry Truman dropped the first atomic bomb. If Trump uses nukes after 81 years, what will stop Vladimir Putin from nuking Ukraine?
