The Coalition against ISIS Hits Road Blocks

Turkey today shot down a Russian warplane near the Syrian border. Vladimir Putin called it a "stab in the back." Word came as French President Holland was at the White House hoping to build a coalition against ISIS that would include Russia as well as the US. At their news conference, President Obama called Russia a welcome part of the coalition fighting in Syria, but added, "The challenge has been Russia's focus on propping up Assad instead of ISIL."
