North Korea

Deep Shit are the only people who want America Nuked or EMPed. NK know they would all die in a Nuclear Holocaust

we'd still totally fuck them up and with a vengeance. NK has no reason to actually attack us, they're just posturing to figure out what advantage it will give them and keep the American allies in Asia on edge. They could decimate half the country, which they wouldn't be able to, and we'd still slap their shit so hard and hang their leaders
