The Obama administration is considering a plan to coordinate air strikes on Nusra Front and Islamic State militants in Syria if Syria's government stops bombing 'moderate' rebels, US officials said on Thursday.
The US backs the 'moderate' rebels, who are under pressure from Islamic State and government forces, but the plan depends in part on whether Russia is willing to press Syrian President Bashar al-Assad, its ally, to stop bombing them. Many US officials and outside experts doubt Moscow is willing to do that.
It would also require moderate opposition forces to disentangle themselves from Nusra and move into identifiable areas where they would be vulnerable to government and Russian air attacks.
Although Russia says it has targeted Islamic State, most of its strikes have been on the US-backed moderate rebels, who distrust the Assad government which has caused most of the ceasefire violation, as claimed by the moderate rebels and Washington.
"If the moderates separate themselves from Nusra, the Russians and Assad will immediately target them," said Chris Harmer, an analyst with the Institute for the Study of War. "The idea that the moderate rebels will separate themselves from Nusra is just not going to happen. It (the administration plan) is a Hail Mary pass that is dead on arrival."
"It’s staggering to me that anybody, even during the fifth year of this civil war, thought this would be a good idea," said Harmer.
The Washington Post, which first reported the plan, said the Obama administration has submitted a written proposal to Moscow, but two US officials, speaking on condition of anonymity, said that while the plan is under discussion within the administration, no decisions have been made.
A 'Hail Mary'pass?
That Washington is even considering such a plan, however, reflects the unravelling of a February 27 cessation of hostilities agreement that was supposed to bring some calm to a country riven by five years of civil war and promote a political settlement, as well as the weakness of the US-backed moderate opposition forces.
In one sign of their predicament, US-backed Syrian rebels on Wednesday were pushed back from Al-Bukamal, an Islamic State-held town on the Iraq border, suffering casualties and seeing some of their fighters and arms captured, a rebel source said.
Finally, targeting the Nusra Front could end up boosting the popularity of the al Qaeda affiliate, which is widely hailed by anti-government Syrians as the most effective fighting force seeking to oust Assad.
Prospects for a political deal to end the conflict appear dim, not least because there is no agreement on the future of Assad, whom the US wants to step down, but whom Russia has supported with its military intervention since last September.
UN Syria envoy Staffan De Mistura is in Washington this week to meet senior US officials to discuss efforts to reduce attacks on civilians and the provision of humanitarian aid as he "continues to work to advance a political transition," National security council spokesman Carl Woog said on Thursday.
