I personally believe ISIS will never become a serious and credible state in the world.
They have made it clear that they don’t care much for international diplomacy or law and that only Sharia can be used to govern their new state.
A fanatical force like this does well at first; they carry out brutal acts, capture swathes of land, steal, murder, rape, perform forced conversions to Islam and run a well oiled recruiting machine but this can only last for a while because sooner or later their resources are depleted and the circus over.
So you wanna crush ISIS? Better act fast and swift… Here’s a short list of their Achilles’ heal.
1. ISIS is militarily overextended and hopelessly ineffective against a trained and well-equipped army. Although they’re led by a few savage Chechen’s and some Arab militants who answer to a mysterious bearded man who calls himself “Abu Bakr Al-Bagdadi”, it will take only one crushing defeat to completely demoralize their forces, who so far have only shown their prowess in gunning down heretics (Shia, Ezidi, Christians and some ethnic Turkmen), beheading children and foreigners and stealing some old military equipment left behind by the US and Russia.
