Now, I told you earlier all the talk of America's economic decline is political hot air. Well, so is all the rhetoric you hear about our enemies getting stronger and America getting weaker. Let me tell you something: The United States of America is the most powerful nation on Earth. Period. [Applause] Period. It's not even close. [Applause] It's not even close. It's not even close. We spend more on our military than the next eight nations combined. Our troops are the finest fighting force in the history of the world. [Applause] All right. No nation attacks us directly, or our allies, because they know that's the path to ruin. Surveys show our standing around the world is higher than when I was elected to this office, and when it comes to every important international issue, people of the world do not look to Beijing or Moscow to lead. They call us. So I think it's useful to level set here, because when we don't, we don't make good decisions.

Now, as someone who begins every day with an intelligence briefing, I know this is a dangerous time. But that's not primarily because of some looming superpower out there, and it's certainly not because of diminished American strength. In today's world, we're threatened less by evil empires and more by failing states.

The Middle East is going through a transformation that will play out for a generation, rooted in conflicts that date back millennia. Economic headwinds are blowing in from a Chinese economy that is in significant transition. Even as their economy severely contracts, Russia is pouring resources in to prop up Ukraine and Syria, client states that they saw slipping away from their orbit. And the international system we built after World War II is now struggling to keep pace with this new reality. It's up to us, the United States of America, to help remake that system. And to do that well, it means that we've got to set priorities. Priority number one is protecting the American people and going after terrorist networks. Both Al Qaida and now ISIL pose a direct threat to our people, because in today's world, even a handful of terrorists who place no value on human life, including their own, can do a lot of damage. They use the Internet to poison the minds of individuals inside our country. Their actions undermine and destabilize our allies. We have to take them out.

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.

Now, fortunately there is a smarter approach: a patient and disciplined strategy that uses every element of our national power. It says America will always act, alone if necessary, to protect our people and our allies, but on issues of global concern, we will mobilize the world to work with us and make sure other countries pull their own weight. That's our approach to conflicts like Syria, where we're partnering with local forces and leading international efforts to help that broken society pursue a lasting peace. That's why we built a global coalition, with sanctions and principled diplomacy, to prevent a nuclear-armed Iran. And as we speak, Iran has rolled back its nuclear program, shipped out its uranium stockpile, and the world has avoided another war.

That's how we stopped the spread of Ebola in West Africa. Our military, our doctors, our development workers--they were heroic; they set up the platform that then allowed other countries to join in behind us and stamp out that epidemic. Hundreds of thousands, maybe a couple million, lives were saved.
