No disrespect to you my Iranian friend, but Iran isn't capable of stopping any military action either by GCC+Turkey or NATO or both. The game changer in the Syrian conflict now is air power. The Air power is in favor of Turks, and in the GCC. As per my calculations Turkish air force alone is capable of destroying and establishing a no fly zone over Syria, without any help from outside. If you add GCC air forces ie Saudi, UAE,Qatari,Jordanian and Egyptian....well you are talking about the most powerful air force alliance in the region. If they establish a no fly zone, the Asadian armor will be obliterated by the FSA and by CAS provided by these air forces. They don't need to have boots on the ground, they just need to destroy every winged asad asset and only then the FSA can take the fight to Asad's bunker. Capability is there.....will or ethical responsibility simply isn't, that is replaced with rhetoric.
