“… “It’s a Donilon call at the end of the day,” the official said, referring to National Security Advisor Tom Donilon, who is leading a complicated interagency policy process on the Syria crisis. “There’s not enthusiasm but there are differences of opinion about a no-fly zone,” the official said. “There is no rush to do it.”The Assad regime’s lack of use of fixed-wing aircraft was cited internally as a reason not to declare at no-fly zone and that reason no longer applies, the official argued. Opponents of a no-fly zone have also argued that the Syrian internal opposition had not formally requested it. That reason is also no longer operative.
