By now it is clear that Iran and/or Russia will never give up on Syria, and as it seems the west + Wahabi Gulf dictators are working on plan-B to invade Syria, attack ISIS regions, train the so called 'moderate terrorists' and enable them to take over ISIS cities... then from there they will/might expand the 'moderate terrorists' rules and will help them directly to go after Syrian army. Is it a crucial time for Shias/Iran to make sure that doesn't happen and a massacre of Shias/Alawites and other Syrians who reject Takfiris rules and laws does not happen? And prevent the western-Wahabi alliance to overthrow the Syrian government? Should Iran just send troops or should it just increase its aids to Shia groups/Syrian government/Hizbullah instead?
