And I also know that there’s some who have asked questions about why are we still in Afghanistan? What does this mean? What’s its purpose? Understand we would not deploy our own troops if this mission was not indispensable to our common security. As President, I can tell you there’s no decision more difficult, there’s no duty more painful, than signing a letter to the family of somebody who has died in war.
So I understand that there is doubt about this war in Europe. There’s doubt at times even in the United States. But know this: The United States of America did not choose to fight a war in Afghanistan. We were attacked by an al Qaeda network that killed thousands on American soil, including French and Germans. Along the border of Afghanistan and Pakistan, those terrorists are still plotting today. And they’re — if there is another al Qaeda attack, it is just as likely, if not more, that it will be here in Europe in a European city.
So I’ve made a commitment to Afghanistan, and I’ve asked our NATO partners for more civilian and military support and assistance. We do this with a clear purpose: to root out the terrorists who threaten all of us, to train the Afghan people to sustain their own security and to help them advance their own opportunity, and to quicken the day when our troops come home.
We have no interest in occupying Afghanistan. We have more than enough to do in rebuilding America. (Applause.) But this is a mission that tests whether nations can come together in common purpose on behalf of our common security. That’s what we did together in the 20th century. And now we need an alliance that is even stronger than when it brought down a mighty wall in Berlin.
That’s why we applaud France’s decision to expand and deepen its participation in NATO, just as we support a strong European defense. That’s why we welcome Croatia and Albania into the fold. And that is why we must ensure that NATO is equipped and capable of facing down the threats and challenges of this new age. This is one of our central tasks.
And we also know that in the 21st century, security is more complex than military power. This is the generation that must also stop the spread of the pollution that is slowly killing our planet, from shrinking coastlines and devastating storms to widespread misery and famine and drought. The effects of climate change are now in plain sight.
Europe has acted with a seriousness of purpose that this challenge demands. And in the last few months I’m proud to say that America has begun to take unprecedented steps to transform the way that we use energy. We appointed a special envoy to help us lead a global effort to reduce the carbon that we send in the atmosphere.
