So what should the "ginger twat" do about a mad dictator with nuclear armed ICBMs that can reach US and who keeps saying he is going to use them?

The only suggestion so far was in Backwoodsman's link, which was to hope that there might be a coup in NK some time soon!
Anyone holding their breath for that happening?

Trump only inherited this long standing problem a few months ago.
What did previous administrations do about it?
Any lessons from them?
