In about two thousand words, Khamenei discussed the reasons for the worldwide wave of terrorism,[1] calling it "our common worry".[5] Among them he noted the impact that major Western powers had with their military operations in the Islamic world.[1] He mentioned United States's alleged role in the evolution of terroristic groups like al-Qaeda, the Taliban, and ISIL—"the spawn of such ill-fated pairings with imported cultures."[6]
Khamenei also pointed out the "oppressed people of Palestine", who "have experienced the worst kind of terrorism for the last 60 years."[6] For this, he criticised Israel, its allies and international organisations.[7]
