"As Commander-in-Chief, I have no greater responsibility than keeping this country safe. And no decision weighs on me more than when to deploy our men and women in uniform. I’ve made it clear that I will never hesitate to use our military swiftly, decisively, and unilaterally when necessary to defend our people, our homeland, our allies and our core interests. That's why we’re going after al Qaeda wherever they seek a foothold. That is why we continue to fight in Afghanistan, even as we have ended our combat mission in Iraq and removed more than 100,000 troops from that country. There will be times, though, when our safety is not directly threatened, but our interests and our values are. Sometimes, the course of history poses challenges that threaten our common humanity and our common security — responding to natural disasters, for example; or preventing genocide and keeping the peace; ensuring regional security, and maintaining the flow of commerce. These may not be America’s problems alone, but they are important to us. They’re problems worth solving. And in these circumstances, we know that the United States, as the world’s most powerful nation, will often be called upon to help. In such cases, we should not be afraid to act — but the burden of action should not be America’s alone. As we have in Libya, our task is instead to mobilize the international community for collective action. Because contrary to the claims of some, American leadership is not simply a matter of going it alone and bearing all of the burden ourselves. Real leadership creates the conditions and coalitions for others to step up as well; to work with allies and partners so that they bear their share of the burden and pay their share of the costs; and to see that the principles of justice and human dignity are upheld by all."
