Every President is a threat. This one is also a bit of a ****. Again, hardly new territory.
THe extent to which he can be considered a threat on the global stage rests on the assumption that diplomacy and sabre rattling depend on one individual. THey dont.
Trump is not going to accidentally start a war any more than Bush made a decision to invade Afghanistan and Iraq on his own. There are many, many people at the table and it is their job to make sure that global peace isnt reliant on the President's mood.
Yes. We have been essentially sold the notion of our leading politicians as interchangeable, platitude-mouthing placemen for so long that we are now incapable of dealing with someone who doesn't censor himself, rocks up and says what he means and does what he says he's going to do. Hence my belief that he is 'a good thing'.
