From pg. 166

Renowned Jewish historian Bernard Lewis explained the Islamic resentment of the West and its influence in his writing "The Roots of Muslim Rage":

The Muslim has suffered successive stages of defeat. The first was his loss of domination in the world, to the advancing power of Russia and the West. The second was the undermining of his authority in his own country, through an invasion of foreign ideas...and ways of life and sometimes even foreign rulers or settlers, and the enfranchisement of native non-Muslim elements. The third—the last straw—was the challenge to his mastery in his own house, from emancipated women and rebellious children. It was too much to endure, and the outbreak of rage against these alien, infidel...forces that had subverted his dominance, disrupted his society, and...violated the sanctuary of his home was inevitable. It was also natural that this rage should be directed primarily against the millennial enemy and...draw its strength from ancient beliefs and loyalties.

Bernard Lewis, "The Roots of Muslim Rage," Atlantic, September 1990.

And from pg. 177:

The ravaging death toll of the radical Islamic extremists continues: the Islamic State (ISI, ISIL, and ISIS), Boko Haram of the African continent, Al Qaeda, and the Taliban are responsible for the majority of all terrorist murders worldwide. Many of these horrific murders are carried out through public executions, crucifixions, and beheadings. In fact, there are reports of "a park in Mosul, where they [ISIS] actually beheaded children and put their heads on a stick.
