Autoboomers have been busiy around the globe, having taken out a bus of Israeli tourists in Bulgaria and an anti-terror Muslim leader in the Russian subpart of Tartarstan. The second bombing has echoes of Boko Haram's offing of a traditional Muslim leader in Nigeria, as both represent an establishment form of Islam that is at odds with the desire to create a reactionary theocracy.
The first bombing on the list reminds us of the spot that Israel plays on the haram-list of Muslim radicals; there isn't any strategic benefit to killing off a bunch of Israelis heading to a beach resort. You can see the logic of taking out leaders as a way of showing the cost of being against their version of sharia, but the Bulgarian bombing is just designed to give vengeance to past grievances against Jews and Israel.
Civil war amongst Muslims on one hand in at least two countries outside the Middle East and a possible Hezbollah operation on the other; at least Israel is pointing fingers at them and their Iranian friends. That could be a precursor for what we might see if Israel does pull the trigger on an anti-nuke strike on Iran.
