(CNN) -- As the terrorist group the Islamic State of Iraq and Syria (ISIS) continues to capture and control more territory in Iraq and Syria, it is important to realize what is at stake in the region and for the American people. The challenge that ISIS poses is not just to Iraq's stability but also to U.S. security. ISIS is a terrorist group with their own army and bank account that has a clear and growing ability to conduct terrorist attacks against the Iraqi government, Americans and U.S. interests, and even the U.S. homeland. ISIS, although loosely affiliated with al Qaeda, is in many respects even more extreme in its methods and its brutality than the terrorists who plotted and carried out 9/11.

None of the options before us are ideal, but the question is whether we take action against ISIS now or deal with the consequences later here on @placeholder soil.
