What is the reason behind Russia and Syria's fight against foreign Islamist terrorists in Syria and Iraq and what is the author's opinion on the matter?
Russia and Syria are fighting foreign IS and other Islamist terrorists seeking to transform Syria/Iraq into a fundamentalist Islamic state or caliphate. Tens-of-thousands of Muslims went to Syria from all parts of the world in pursuit of their dream of an Islamic paradise (hell to most people). These are invaders, terrorists and it is right they should be exterminated.
