We owe our World War II veterans - and all our veterans - a debt we can never fully repay.

I am confident that in the end freedom and democracy will prevail over terror and tyranny. We will win this war on terror - and when we do Americans, the British, Iraqis, and people around the world will be more secure.

In remembering those who lost their lives in the London attacks and the September 11th attacks we continue our commitment to fighting for freedom, democracy and justice.

Leaving Iraq without military assistance during its transition, and before it is stable enough to ensure its own citizens' security, would pose a tremendous risk. We must complete our mission.

Since September 11th Congress has created the Department of Homeland Security, more than doubled the homeland security budget and implemented a bipartisan overhaul of our intelligence systems.

Those who committed these cowardly acts may believe that they have shaken our resolve to defeat terrorism. They could not be more wrong.

In the over two centuries since the signing of the Declaration of Independence, millions of Americans have bravely served our nation in uniform so that all generations can continue to enjoy those same liberties.
