Let me ask then what Russia is supposed to do with situation with Syria and Iraq? remember that Saudis and Turks go for war in 7miles boots.
Only a stable country can clean house of ISIS elements.
So step one in Syria is to get the various groups who are worth cooperating with together to cooperate.
That means the Syrian Army, the Kurds, and the anti assad forces need to get together and stop fighting each other with the agreement that when ISIS is fucked that first of all everyone will lay down their weapons and then solve the problems at the ballot box and through politics.
Violence is no way to create a country... Israel was created in violence and the violence continues because neither side listens and uses violence to get their way or to protest not getting their way.
In Iraq Russia can provide weapons and ammo and give advice and support. At any stage if Iraq asks for more then Russia will likely oblige but until they ask they should not make presumptions... at the end of the day it is up to Syria and Iraq to solve some serious fundamental problems that allowed ISIS to grow so strong in the first place...
