After years of denial, the U.S. response must now go beyond countering ISIS in Iraq and Syria.
As Islamic State advances in the northern Syrian province of Aleppo, there is a deadly twist in the war. The radical Islamist group, also known as ISIS or ISIL, is now expanding in roughly a dozen countries across Africa, the Middle East and Asia by exploiting local grievances, doling out money and leveraging its battlefield successes.
Even as the United States struggles to combat Islamic State fighters in Iraq and Syria, swift U.S. action is urgently needed in these new Islamic State outposts to stop and ultimately reverse the group’s spread. The May 29 suicide bombing of a Shiite mosque in Saudi Arabia, the second recent attack on that predominantly Sunni nation, shows how undaunted Islamic State has become.
