Right, and the alawites are the minority Shia, who are receiving tons of external support from other Shia rules countries. Meanwhile the rebel are Sunni's who are primarily getting external support from Sunni countries.
The idea that because it is "just the middle east" doesn't make it not involve the world however. Who's been supplying the ammunition, food, medical supplies for all these fighters... it certainly isn't being produced in syria.
Other countries sending supplies to varied sources still do not make it a world war in its current shape, its a conflict concentrated in a fairly small country. In WW2 the whole of europe was in flames with war efforts going on in large parts of africa, the whole pacific ocean and on asian mainland while also stretching into russia from the eastern front. What is going on in Syria is not even close to that scale.

You said WORLD war, right?
No matter how much we want to keep peace and how much afraid the nuclear owners are of using their arsenals, as the time passes we're more and more closer for firghting for natural resourses. If we manage to keep the world civil for like 50 more years the resourse war will start inevitably. Most likely non-nuclear war then.
And here it goes: who has "too much resourses, which is even unfair to own alone"? Russia, and those of oil-makers of arabian world who are still untouched by those times.
So the targets are clear. Who will want to make them share? All others together, not one country.
That's a WW.
Hopefully by that time humanity will pass the hydrocarbons stage of energy production so there will be less reasons for such a scenario.
The nerve is called the "nerve of awareness". You cant dissect it. Its a current that runs up the center of your spine. I dont know if any of you have sat down, crossed your legs, smoked DMT, and watch what happens... but what happens to me is this big thing goes RRRRRRRRRAAAAAWWW! up my spine and flashes in my brain... well apparently thats whats going to happen if I do this stuff...
That's how economics works. We don't pull it out of the ground right now because it's not economical to do so. The costs of getting at it outweigh the money to be made from the oil that can be obtained.
As conventional oil dries up, it gets more expensive. As it gets more expensive, it becomes more cost effective to pull the more difficult oil out of the ground.
