You should consider what the enemies of the world of Islam are doing in order to create a split in the Islamic Ummah. You should consider how much money they are spending in order to line up different groups of Muslims against one another. It is obvious that one of the goals behind the current bloody events is to indiscriminately kill or disable Muslims. You saw one example of these events in Iraq yesterday, and many similar events are currently happening in Pakistan and other parts of the world. Fomenting discord between Shia and Sunni Muslims is one important goal behind these events.
