@Olivier5,
I don't think he is dangerous at all. What I find dangerous is the increasingly disruptive behavior of very left wing Democrats in elective office. Trump has been far less accommodating to Putin than was his feckless predecessor. I'll agree he initially expressed a desire to improve our relations with Russia, however that is very much in keeping with his overtures to China. N Korea and even the EU - very friendly, but he has an agenda he wishes to pursue with each. I find it refreshing.
We'll know the results of the Brazilian election in a couple of weeks. A conservative candidate is likely to win in any outcome, and this is an obvious direct consequence of the revulsion of Brazilians with the corruption and economic policies Workers Party governments of the past 15 years.
