US Presidency
2009

For when we don't, our actions appear arbitrary and undercut the legitimacy of future interventions, no matter how justified. And this becomes particularly important when the purpose of military action extends beyond self defense or the defense of one nation against an aggressor. More and more, we all confront difficult questions about how to prevent the slaughter of civilians by their own government, or to stop a civil war whose violence and suffering can engulf an entire region. I believe that force can be justified on humanitarian grounds, as it was in the Balkans, or in other places that have been scarred by war. Inaction tears at our conscience and can lead to more costly intervention later. That's why all responsible nations must embrace the role that militaries with a clear mandate can play to keep the peace. America's commitment to global security will never waver. But in a world in which threats are more diffuse, and missions more complex, America can not act alone. America alone can not secure the peace. This is true in Afghanistan.
