In international politics the concept of "legit" is extremely vague. Lets picture a scenario here, if a brutal dictatorship goes on a killing spree just so he could retain absolute power and start displacing and killing his own compatriots systematicly, would it be oke if that very same dictatorship is asking help from lets say, other dictatorships to do his dirty work? Would that dictatorship still be a legit ruler of the country? Only in name buddy, only in name. Take a good look at Libya and ask yourself which is the legimate goverment there.
Turkey was training and arming thousands of moderate FSA fighters. If we are talking about morality here i would chose them over some brutal shia puppet dictator that prefered to throw his country into civil war instead of relinquish some of his power for the greater good and unity of his country. I hope they will chop his head of and shitt down his neck with a good public display.
When Iran stops supporting Yemeni terrorists, Hezbollah, dictatorships and etc etc. Are you people allowed to talk about morals and who the "real" terrorists are. Tell me again how Turkey is the bad guy for pissing on Iranian attemps at desperatly retaining control over their little puppet, that borders Turkey. Tell me about who the expansionist is
Piss off man.
I would love to see Ahmedinejad face when Turkey crushes your little dreams of controlling the region.
The average Iranian here is like "Turkey supports terrorist in Syria" -> Hezbollah, Yemen and Syria in the meantime.
