I would advise Putin to be careful what he wishes for. A loose cannon would advise against behaving in as out-of-control a way as Trump.
I am afraid that I doubt I will be able to support the US in any war engineered by Trump. With such a President, the US is likely the problem.
The world is in real trouble. It is in the path of an irrational, emotional, knee-jerk superpower. Hopefully Trump can be removed from office swiftly once one of the many likely issues surfaces. Even Mike Pence would seem like a relief from this guy.
Almost makes me feel religious. There must be a God with a cynical sense of humour up there to visit such a situation upon us. If we get through it, they'll be telling scary bedtime stories about this for generations.
