[Platapus]

I would opine that the chances of KJU initiating an attack, nuclear or otherwise is approximately zero. KJU may be a ruthless sadistic crummy guy but he is not stupid nor suicidal. KJU wants KJU to survive and he would prefer surviving in a surviving DPRK where he can continue being a crummy guy.

However, The chances of KJU attacking, nuclear or otherwise in retaliation are higher. If he feels that his control over the DPRK is threatened (regardless of whether it is actually threatened or not) and he feels that he has no other choice, he will use what he has.

The key is not putting KJU in that position. That means ratcheting down the the threats coming from the US, for starters. We need to make it very clear that we are not interested in forcing any regime change, but at the same time would support one.

Let him play in his sandbox with his toys. When dealing with someone who may be governed more by emotional responses as opposed to rational thought, you don't want to back him into a corner where he may feel that he has "nothing to lose".
