7 charts on how the world views President Obama | Pew Research Center
Actually. President Obama's image is good in most of the World.
I doubt if Trump's is.
Trump is no Hitler though. That disgraces the memory of all of Hitler's millions of victims. Trump is an opportunistic demagogue playing on fear and prejudice but I certainly doubt he has any gas chambers and the like planned for huge groups of people including those who stand up to him.
I do worry about this man's temperament and the prospect of nuclear war with China, Russian, Iran, Syria, the Taliban, ISIS, or some other power.
