AOA, Good to see you back on the forum brother Dana!
As respected Dr. Shabbir has pointed out in his book "Islam a True History and False Beliefs", these conspiracies against Islam had started a few centuries after the golden periode of 'Khelaphet-e-Rashida'. a seed of discord was planted among Muslims and that resulted in the degenerated version of Islam, that is being followed since then. It created a rift among Ummah and hence divided them into so many different sects. But despite their religious differences, blood shed
was a rarity, although it did happen. The hallmark of this century is the Muslim killing Muslim in cold blood. I agree with you that external forces are fully supporting these violent groups to carry out their murderous agenda. As you pointed out if these external forces have their vested interests in the region, they will keep these conflicts alive, untill the ground is clear for them to show up as occupiers disguised as peace makers. "There are deeper reasons than just dialect & religion that are causing these issues".
