On Sept. 11, 2001 Islamic fundamentalism became a permanent and unwanted fixture in our lives. We thought with the death of Osama bin Laden and our military withdrawals from Iraq and Afghanistan, we'd return to the way things were on Sept. 10, 2001. Unfortunately, ISIS has made this impossible. As soon as ISIS finishes their power consolidation they will be stronger and more deadly than both al-Qaida and the Taliban combined. And they will come after us.
