US plan for proxy army to fight Isis in Syria suffers attack -The Guardian

The US strategy of backing the Kurds and Shi’a against ISIS has had some success. However, their strategy of simultaneously supporting “moderate” anti-regime forces in Syria is struggling. This is troubling for several reasons. First, the weapons the US is providing to groups like the Syrian Revolutionary Front (SRF) may find their way into hands of IS if those groups are defeated. Secondly, there is growing resentment towards US policy that weakens their position in Syria. According to one refugee: “It is obvious that the US is supporting Assad,” he said. “Don’t bother trying to argue with me or anyone else about it. They are aiding the war against us. Their leaders are weak and they are liars.”
Consequently, “The US defence secretary, Chuck Hagel, is reported to have warned national security adviser Susan Rice of a blowback among opposition communities in northern Syria because US strategy against Assad has not been clearly defined.”
This may eventually also put strains on their partnerships with countries like Saudi Arabia and Turkey in the anti-IS coalition. These countries have predicated their support for the US position on the assumption that the US would back regime change in Syria. If the US cannot deliver, their support may waver.
