Wth with the people thinking Turkey is in trouble if the Syrians attack? In terms of weapons and equipment Turkey can face both Greece and Syria in the same time and still win. In terms of weapons and equipment that is, not including the decisions people do that can affect if a war does happen. A full-scale war will never happen or else Syria will be crushed in a few moments just when it begins. They know it, Turkey knows it, Greece would surely as hell knows that attacking Turkey with Syria is the worst thing to do as well. If a shooting war does happen, it'll be just a regional conflict or just a skirmish and probably just would take a short time before it ends. Easy as that.

Also, Syria surely isn't having any western support. Russia isn't hostile with the western powers anymore(the cold war is long over). China, well... it won't be in the best interest of China to support Syria. There would be simply no gains in it and China is already facing deep**** here in South East Asia for killing Filipino fishermen which could start a war. Anyway, any country smaller than the 3 powers namely, China, US and Russia won't be enough to support Syria and make them that brave(even if it's strong enough as to combine the 3 European powers). Also, if Syria would invade Turkey, Israel can find an excuse to invade parts of Syria and start a chain and another damned major regional conflict(not really a good chance of happening though).
