The DP does not take Kim seriously.

Vastly more people are interested in the starting quarterback for the Broncos than WW III which would probably not only annihilate the Broncos, but most living creatures.

Please see post to Burey above.  Trump is giving fair warning not only to North Korea, but to Iran, Pakistan, et al.

Thus far, Trump has recognized and tried to deal with the existential threat of having a madman with nukes.  Trump is not going to allow this madman to get hydrogen bombs on ICBMs.

His reasoning is clear.  It is better that there are hundreds of thousands of casualties now (mostly non-American) rather than hundreds of millions if Kim has thermonuclear capability.

"Strategic patience" was a worse strategy.  Kim is politically isolated now and if Kim gives a reasonable excuse -- e.g. nuclear test, attack on Guam, test of Taepodong-2 -- then Trump will have sufficient cover to terminate Kim.

You are quite right to be extremely scared.  Who knows how this will end?
