I am surprise that it "escalated" only in 2014 when the West has been sowing death and destruction in the Muslim world (as they regularly do in other parts of the world) way earlier than 2014.
"[...] to the extent that the Muslims blood became the cheapest and their wealth as loot in the hands of the enemies. Their blood was spilled in Palestine and Iraq. The horrifying pictures of the massacre of Qana, in Lebanon are still fresh in our memory. Massacres in Tajikistan, Burma, Kashmir, Assam, Philippines, Pattani, Ogaden, Somalia, Eritrea, Chechnya, and in Bosnia-Herzegovina took place, massacres that send shivers in the body and shake the conscience. All of this and the world watch and hear, and not only didn't respond to these atrocities, but also with a clear conspiracy between the USA and its' allies and under the cover of the iniquitous United Nations, the dispossessed people were even prevented from obtaining arms to defend themselves."

"The events that affected my soul in a direct way started in 1982 when America permitted the Israelis to invade Lebanon and the American Sixth Fleet helped them in that. This bombardment began and many were killed and injured and others were terrorised and displaced. I couldn't forget those moving scenes, blood and severed limbs, women and children sprawled everywhere. Houses destroyed along with their occupants and high rises demolished over their residents, rockets raining down on our home without mercy. " OBL
