An ISIS e-book on how to accomplish their caliphate goal of sacking Rome stresses enlisting “the Islamic State’s secret weapon = secret white converts” to take on Italy.

Much of the book, “Black Flags from Rome,” is dedicated to laying out a case for why Muslims in Europe should rise up and assist ISIS from within, citing justifications for discontent from modern-day anti-immigration protests back to post-Ottoman creation of Muslim “ghettos.” […]

The Islamic State, it says, “re-awoke” in the midst of Syrian turmoil and “the exit of American troops from Iraq in 2010.”

“The Western powers would not get involved in physical ground combat because they had just withdrawn from a failed war in Iraq (their public wouldn’t be happy with it.) This opportunity gave the Islamic State to grow stronger, with more fighters and more territory and resources as the world watched on. Those who had left Europe to join the Islamic State would now be able to help other Europeans’ get into Syria… Here they could learn basic armed/shooting combat, assassination techniques, how to make explosives from homemade materials etc.”
