There is nothing any of us can do about it, but the situation developing with North Korea is very frightening. It is terrifying to see an unstable man with his hands on nuclear weapons. And then there is Kim-Jong Un.
It appears, from a distance, that Trump is enraptured with the power to order airstrikes, unconnected with any coherent policy or understanding of the situation on the ground. Should he order the use of tactical nuclear weapons, there will be no going back. I have no idea whether the North Korean ruler is crafty or unhinged, but I think I can make a pretty good assessment of the American ruler, and nothing I see is at all reassuring.
