The US is about to get a new Commander-in-Chief - Does he represent a danger to world security?

This twitter really disturbes me:

Intelligence agencies should never have allowed this fake news to "leak" into the public. One last shot at me.Are we living in Nazi Germany?

To me, this is a kick in Angela Merkels` butt, possibly US` most important ally. Most importantly though is his mistrust in his intelligence community. If he decides to go it alone; listen more to his sons and son-in-law than CIA/NSA/Pentagon, the world may be in deep shit.
