In a world of complex threats, our security and leadership depends on all elements of our power - including strong and principled diplomacy.

We cannot continue to rely only on our military in order to achieve the national security objectives that we've set. We've got to have a civilian national security force that's just as powerful, just as strong, just as well-funded.

To all those watching tonight from beyond our shores, from parliaments and palaces, to those who are huddled around radios in the forgotten corners of the world, our stories are singular, but our destiny is shared, and a new dawn of American leadership is at hand.

When we think of the major threats to our national security, the first to come to mind are nuclear proliferation, rogue states and global terrorism. But another kind of threat lurks beyond our shores, one from nature, not humans - an avian flu pandemic.

People of Berlin - people of the world - this is our moment. This is our time.

We need to keep making our streets safer and our criminal justice system fairer - our homeland more secure, our world more peaceful and sustainable for the next generation.
