Syria was limited economically, UN limitations, after they used chemical weapons the western world gave rebel groups weapons and communication devices, and a lot of Syrian military defected from Assad's Tyranny to rebel groups, which battled each other as well as Assad' loyalists, and the eventual result has lead to a well armed Jihadi army that marches out into Iraq for wealth and powers and to recruit a New Army of Iraqis who join them, as well as oil money to be made to fund their holy war.
the eventual goal for Isis is a calafate, a great nation of islam run by a supreme religious leader, it would make Iran and Saudi Arabia look like wet liberals as it creates a war economy to topple other nations much as in the old days of islam, at the time of the Prophet Muhammad.
maybe the lesson to learn is don't just try to topple dictators like Assad by poxy, the rebels became dominated by Jihadis, if only the west had not allowed communication devices and armys to help free them in their Syrian spring, it would have been better of fighting side by side with them to flatten Assad's tyranny and allow freedom to return. As it turned out it's out of control and threatens to mess up one our last the major fuck ups, Iraq, and not to mention that Palestine is being battered by the Israelis, and Libyans are fighting eat others, and the issue of African jihadis is still massive, from somalia to Mali, some Americans called the war on terror the long war, boy were they right!
