And every example I gave was of countries failing to unite behind what was supposed to be a unifying belief. Even India at the time of the British occupation was a series of kingdoms. Christians couldn’t unite even with the pope offering to pay for the fight against the Turks, and they all wanted a Christian World or believed it was inevitable. Muslims may want a return of the Caliphate but apostates or even worse than infidels. Expediency may allow them to work together temporarily like Hitler and Stalin, but the whole time they will be plotting to stab each other in the back and they all know it. The only possibility of the Muslim World uniting would be for the west to declare war on Islam and even then it would be very unlikely. A Muslim is far more apt to die at the hands of another Muslim.
Believe what you want, but the OIC is uniting them. Whether they fight amongst each other is irrelevant, as they are on a worldwide movement to dominate the world. There is not one country speaking out against the Sharia push.
