But as we focus on destroying ISIL, over-the-top claims that this is world war III just play into their hands. Masses of fighters on the back of pickup trucks, twisted souls plotting in apartments or garages, they pose an enormous danger to civilians; they have to be stopped. But they do not threaten our national existence. That is the story ISIL wants to tell. That's the kind of propaganda they use to recruit. We don't need to build them up to show that we're serious, and we sure don't need to push away vital allies in this fight by echoing the lie that ISIL is somehow representative of one of the world's largest religions. We just need to call them what they are: killers and fanatics who have to be rooted out, hunted down, and destroyed. And that's exactly what we're doing. For more than a year, America has led a coalition of more than 60 countries to cut off ISIL's financing, disrupt their plots, stop the flow of terrorist fighters, and stamp out their vicious ideology. With nearly 10,000 airstrikes, we're taking out their leadership, their oil, their training camps, their weapons. We're training, arming, and supporting forces who are steadily reclaiming territory in Iraq and Syria. If this Congress is serious about winning this war and wants to send a message to our troops and the world, authorize the use of military force against ISIL. Take a vote. [Applause] Take a vote. But the American people should know that with or without congressional action, ISIL will learn the same lessons as terrorists before them. If you doubt America's commitment--or mine--to see that justice is done, just ask Usama bin Laden. Ask the leader of Al Qaida in Yemen, who was taken out last year, or the perpetrator of the Benghazi attacks, who sits in a prison cell. When you come after Americans, we go after you. And it may take time, but we have long memories, and our reach has no limits. Our foreign policy has to be focused on the threat from ISIL and Al Qaida, but it can't stop there. For even without ISIL, even without Al Qaida, instability will continue for decades in many parts of the world: in the Middle East, in Afghanistan and parts of Pakistan, in parts of Central America, in Africa and Asia. Some of these places may become safe havens for new terrorist networks. Others will just fall victim to ethnic conflict or famine, feeding the next wave of refugees. The world will look to us to help solve these problems, and our answer needs to be more than tough talk or calls to carpet-bomb civilians. That may work as a TV sound bite, but it doesn't pass muster on the world stage. We also can't try to take over and rebuild every country that falls into crisis, even if it's done with the best of intentions. That's not leadership; that's a recipe for quagmire, spilling American blood and treasure that ultimately will weaken us. It's the lesson of Vietnam; it's the lesson of Iraq. And we should have learned it by now.
