As the Assad regime, backed by Russian air-strikes, opens its offensive on the Free Syrian Army's Southern Front in Daraa governorate—and towns start to fall to pro-regime forces, with thousands fleeing their homes in fear of reprisals—the White House has issued a statement to the rebels, warning, "[Y]ou should not base your decisions on the assumption or expectation of a military intervention by us." This despite Washington's earlier warning to Assad and Putin that any violation of the so-called “de-escalation zones” would have "serious repercussions." Not surprisingly, this betrayal comes just as Trump reportedly told Jordan's King Abdullah II at the White House that he is seeking a deal with Putin on terms for a withdrawal of remaining US forces from Syria. The US has long been constraining the rebel forces from fighting Assad as a condition of receiving aid, insisting they fight only ISIS and other jihadists. Now that ISIS is essentially defeated, we appear to be witnessing the betrayal of the Syrian opposition in a Trump-Putin carve-up deal. (Southern Front logo via Wikipedia)
