Boxed in, NK has several targets in mind and will play the MAD game. Seoul and other parts of SK are a concern in the mediate, however targeting the Takahama nuclear power plant would create more wide-spread destruction, (All without firing a nuke). NK can hit that with ease if they sense any type of attack coming.
You assume they have a missile that can get through the shield and hit with enough power and accuracy to cause a melt in the containment vessel.
Nay, their deterrent is a nuke on Seoul. And they count on the South refusing the US permission.
What they do not realize is the US will put its interests above that of the South, or even Japan, and strike hard and quick.
We must eliminate the threat to the US.
American leaders should have acted long ago, when the Norks were just getting started. The lesson of Neville Chamberlain was never learned by the Bushes, Clinton & Obama. Appeasement with a mad megalomaniac has never worked and never will.
My take on Kim Un is he loves to push the envelope, but is not exactly suicidal. He likes eating and drinking too much to commit suicide. I am betting on him NOT launching weaponized rockets towards US and it’s allies. He is playing the same game the Norks have played for decades, which is to threaten crazy actions and get all sorts of aid and concessions from USA.
