[null and void]

Less known to most folks is there was a Second Korean Conflict from 1966-1969:

Even less known is the simple fact that the 1950-1953 Korean war was never declared over. We have been and still and are at a legally declared state of war with NK since 1950.

I believe this gives a US president the legal right to flatten everything from the DMZ to the Yalu river. Not that it would be a good idea, but under the War Powers Resolution of 1973, he has the authority.

Hi there, nully.

You are correct—we are still in a state of conflict with North Korea. We only have an armistice in place from 1953.

No peace treaty.

That might be the only way to keep an artillery and missile strike from obliterating Seoul. Hit first with everything you have at all the artillery and missile sites and hope you got them all. Counter-battery the hell out of anything that barks afterward.
