ISIS’s Black Flags Are Flying in Europe

“Death to the Jews” chanted the crowd waving the black flags of the Islamic State, or ISIS as it used to be known. They were looking for new supporters for their cause, the creation of a worldwide caliphate answering to the man who now calls himself Ibrahim: a zealot too radical even for Al Qaeda who has stormed through Syria and Iraq carrying out mass executions, crucifying rivals, beheading enemies. But these marchers were not in Syria or Iraq; they were in The Hague in The Netherlands. And their message was one tailored to the disaffected young descendants of Muslim immigrants in Europe.
