I'll give you credit for one thing.... you're very good at making broading sweeping generalisations about things you obviously know very little about, much like Trump himself. What a surprise! Tell me, which countries do you believe are ruled by so called leftists and which are not?
And as far as immigration goes, it's blatantly apparent you don't have a f***ing clue about global treaties, international laws, or anything else that exists beyond your own limited US centric indocrinated worldview.
You're also wrong about Obama. His approval rating by other world leaders was one of the highest ever granted to any US president throughout history, due in part to his vast knowledge of the US Constitution, international affairs, and lived experiences as being 1/2 black, etc, all of which informed his decision making. There were times that I too was totally pissed with some of the policies he enacted due to naivety and/or political pressure, but overall I do think he was primarily an honest and honorable man who sincerely sought to advance what he perceived to be the best interests of the nation.
The same cannot be said about Trump. He's only ever cared about increasing own financial interests, having his ego stroked, and being perceived as a "winner" even when he wasn't and will readily lie, cheat, and/or steal to uphold that image. Even his own sister, who is a retired federal judge, disclosed to her/his niece that Trump paid someone to take his university entrance exams that got him admitted into Penn State and many other sleasy things he did.
