He's now threatening the States themselves.

Whilst I sort of agree, wasn’t the result of their ‘democratic’ election a bit questionable?

Maybe. But would such a 'question' (for instance) give a green light to Canada to bomb the US if Trump decided to install himself for a third term, having lost the election?
It's kinda fascinating, in a ghoulish sort of way, seeing a man who is so obviously both psychologically completely dysfunctional, and whose brain is decomposing in front of the world's eyes, whilst also having the capacity to vaporise the entire planet if he so decided. It seems that there's no-one in his circle who would be prepared to commit him to one of the asylums of which he speaks.
It's the people in his circle,or running that circle, we should be worried about.
