The entire world has been stunned by the refugee crisis unfolding in Europe, the worst since World War II, and particularly horrified by the discovery in an abandoned truck of 71 dead refugees who were believed to be Syrians trying to escape to Germany. But few have had the courage to point the finger at the one man responsible for this humanitarian debacle, President Obama.

What we are watching is more than a human tragedy. It is the direct consequence of the Obama administration’s disastrous Middle East policy, which has destabilized and destroyed Libya, Syria, Iraq and very soon Afghanistan. The important lesson for everyone, including European leaders who once welcomed Obama as their partner, is that when the U.S. decides to retreat from its responsibilities, chaos ensues — and the innocent pay the price.
