Yet tonight, we take comfort in knowing that the tide of war is receding. Fewer of our sons and daughters are serving in harm's way. We have ended our combat mission in Iraq, with 100,000 American troops already out of that country. And even as there will be dark days ahead in Afghanistan, the light of a secure peace can be seen in the distance. These long wars will come to a responsible end.
As they do, we must learn their lessons. Already this decade of war has caused many to question the nature of America's engagement around the world. Some would have America retreat from our responsibility as an anchor of global security, and embrace an isolation that ignores the very real threats that we face. Others would have America over-extend ourselves, confronting every evil that can be found abroad.
We must chart a more centered course. Like generations before, we must embrace America's singular role in the course of human events. But we must be as pragmatic as we are passionate; as strategic as we are resolute. When threatened, we must respond with force -- but when that force can be targeted, we need not deploy large armies overseas. When innocents are being slaughtered and global security endangered, we don't have to choose between standing idly by or acting on our own. Instead, we must rally international action, which we are doing in Libya, where we do not have a single soldier on the ground, but are supporting allies in protecting the Libyan people and giving them the chance to determine their destiny.
In all that we do, we must remember that what sets America apart is not solely our power -- it is the principles upon which our union was founded. We are a nation that brings our enemies to justice while adhering to the rule of law, and respecting the rights of all our citizens. We protect our own freedom and prosperity by extending it to others. We stand not for empire, but for self-determination. That is why we have a stake in the democratic aspirations that are now washing across the Arab World. We will support those revolutions with fidelity to our ideals, with the power of our example, and with an unwavering belief that all human beings deserve to live with freedom and dignity.
Above all, we are a nation whose strength abroad has been anchored in opportunity for our citizens at home. Over the last decade, we have spent a trillion dollars on war, at a time of rising debt and hard economic times. Now, we must invest in America's greatest resource -- our people. We must unleash innovation that creates new jobs and industry, while living within our means. We must rebuild our infrastructure and find new and clean sources of energy. And most of all, after a decade of passionate debate, we must recapture the common purpose that we shared at the beginning of this time of war. For our nation draws strength from our differences, and when our union is strong no hill is too steep and no horizon is beyond our reach.
America, it is time to focus on nation building here at home.
In this effort, we draw inspiration from our fellow Americans who have sacrificed so much on our behalf. To our troops, our veterans and their families, I speak for all Americans when I say that we will keep our sacred trust with you, and provide you with the care, and benefits, and opportunity that you deserve.
