There's a line in the show "Last Resort" (one season, ABC) that you have to make them think "You're just crazy enough (that you might launch nukes)". This is what Trump is doing, essentially. And really, the opinion from the left just helps his strategy because lil' Kim over there has to be thinking daily about if Trump is a crazy enough SOB to launch at them.
I sure hope Trump isn’t cribbing foreign policy strategy from Last Resort...
*For those who didn’t see Last Resort (everyone): While Daveav is comparing Trump to Andre Braugher’s submarine captain character, suffice to say the more obvious comparison would be to the insane President who in the pilot episode randomly nukes Pakistan for no reason other than to basically #MAGA.
