Yezzir. Besides directly threatening us a day ago, they also threatened Australia. The rhetoric is getting pretty alarming. Given Trumps disposition so far, as far as responding to 'red lines', I am pretty sure we will engage in military action against NK.
They can't reach us, but I am genuinely concerned for Japan/SK.
I hope that Americans have enough missiles to shoot down any target with North Korea. But such regimes in NK usually based on lies. I'm not sure their missiles can fly.
