Yemeni opposition versus Syrian (official) opposition

Mohammad sent me this (I cite with his permission):  "notice how the yemeni protesters publicly, explicitly and repeatedly denounce saudi arabian meddling in their country, but the syrian national council always praises saudi? and despite the violence perpetrated by yemeni forces against protesters, no yemeni has called for a no fly zone, unlike in syria where every other day we say huge signs at the protests calling for a no fly zone-even though the syrian air force hasn't been used!  nothing against the syrian people protesting, but this is getting very frustrating."
