Republicans shook hands with Saddam Hussein as he slaughtered and gassed Iranians en mass in their push for regime change back in the 80's, they turned a blind eye when Saddam slaughtered 200k Shia Iraqis back in 1991.
Obama turns a blind eye to Yemen genocide and Bahrain occupation by the Saudis.
My point is, anyone expecting morals or ethics to drive foreign relations policies of the USA is fooling themselves. The republicans massacred the Iraqis while the Democrats starved them to death, and they both deal with war criminals.
