Ummmmmmmmm, for starters killing millions of civilians? Then filling the atmosphere with the soot of nuclear war resulting in global famines? Consider also that 1 singular missile reaching NYC kills 1.5 million Americans in the 1st 24h, and injures 3 million more. You can't 'win' a two sided nuclear war lmao. Only someone completely microwave-brained by ideology and with a deep hatred for human life would consider an offensive first strike.

These days, offensive first strike doesn't need to be nuclear at all. Nuclear will work even worse than conventional (because airborne debris from nondestructive previous nuclear hits may wreck subsequent incoming warheads).
