The history of the debacle in Syria and the Syrian refugees is partially because President Obama refused to act far earlier against the Syrian government, which used chemical weapons. As secretary of State, Hillary Clinton, also bears some responsibility.
When the United States left Germany and Japan after World War II, we left residual troops to prevent what happened in Iraq. The Iraq war was won, and if we had left 10,000 American troops there would be no ISIS. Political decisions have consequences, and Obama and Clinton have to take responsibly for their actions.
