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.
True, kicked the can awhile ago, now this/next generation has to deal with a rogue nuke State. Of course you are going to be called an “isolationists” because you defy the sanctions/Chamberlain approach.
