There is no charity in what Russia has done in Syria.  I am not terrified of Islamic hordes destroying western civilization.  I see it much more likely they will follow the history of their Christian counterparts and engage in a religious civil war among themselves.  In case you haven't noticed, the Sunni and the Shia are not enamored of each other....kind of like Catholics and Prods in Northern Ireland.  I could list many other armed religious conflicts among Christians, but I should think Northern Ireland is recent enough for you to remember.
