A U.S. government source says small arms from the U.S. are starting to head into Syria, funneled by the CIA, which is involved in covert training of rebel forces in Jordan. But a larger U.S. training effort has yet to be approved by the White House. The Pentagon is coming up with options that ramp up CIA training in Jordan and possibly Turkey. Other Arab countries have also expressed interest in helping out. Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, has hinted that the larger-scale training would be done by either Green Berets or conventional U.S. troops, and Sen. John McCain is pushing for this effort. But the effort may have been put on hold given the new diplomatic effort between the U.S. and Russia.
