From President Barack H. Obama's inaugural address, January 20 2009
Recall that earlier generations faced down fascism and communism not just with missiles and tanks, but with sturdy alliances and enduring convictions. They understood that our power alone cannot protect us, nor does it entitle us to do as we please. Instead, they knew that our power grows through its prudent use; our security emanates from the justness of our cause, the force of our example, the tempering qualities of humility and restraint.
We are the keepers of this legacy. Guided by these principles once more, we can meet those new threats that demand even greater effort - even greater cooperation and understanding between nations.
