This war of "Syrian Loyalists" against "Syrian Rebels" is analagous to the war once played out long ago, for the sake of Jews, when "Egypt" fought "Egypt", as it says in Isaiah (19:2):
ואיש ברעהו עיר בעיר ממלכה בממלכה
This is exactly what's happening now in Syria. I said before, in "Syria - A Miracle Unfolds", that a miracle is unfolding before our very eyes. What may well happen is that Israel will be spared, please God, from the necessity of fighting and bloodshed because her enemies are killing each other and downsizing their might. Iran, with its Hizbullah proxy, has already heavily entered into the fray. (Israel can now take relief from the threat to her northern border.) Soon we can expect Turkey to scale up the war as a counter measure to Iran's last move. Who knows how far this will spread?
I don't mean here to prohesize, only to shed light on what is happening from "an End of Days" Jewish perspective, which takes into account the war Moshiach is waging (behind the scenes) against Jewish enemies, by strategically setting enemy against enemy, evil against evil, thereby beginning the sweep up of evil from the world, as he refines the world by preserving the good while eliminating the bad.
Things may look like the rules of Nature are hard at play, but it depends who is doing the looking and the glasses worn by the observer. This observer sees Redemption in the cards.
Rather than fret, therefore, and become overly concerned with mundane politics and "logistical" calculations, it would be far waiser if we continue learning about Moshiach and Redemption, which, as stated here, in "Resuscitating a Dying Counter-Culture", is in and of itself the very best means to gain victory over our enemies, and leave our army experts do their job while we do ours.
