Using the Presidents logic, Putin support terrorism.   Russia has allies in both Iran and Syria, which The President has declared as terrorist nations.   By connection, Trump is OK cooperating with a nation that funds terrorism.     (Must be easier to condemn Qatar than Russia, and sound tough)

Of course the President has also pursued commercial investment in Russia for over a decade.    President Trump is a salesman and if there is money to be made, small details like personal integrity, civic freedoms, political murders, banning a free press, well, what's that got to do with making a few million dollars?

Understanding the President isn't that hard, he's a salesman who cares less about justice than he does profit.   Anything that enriches himself, family, or friends doesn't require a moral compass.
