And in Afghanistan, we're increasing our troops and training Afghan security forces so they can begin to take the lead in July of 2011 and our troops can begin to come home. We will reward good governance, work to reduce corruption, and support the rights of all Afghans, men and women alike. We're joined by allies and partners who have increased their own commitments and who will come together tomorrow in London to reaffirm our common purpose. There will be difficult days ahead, but I am absolutely confident we will succeed. As we take the fight to Al Qaida, we are responsibly leaving Iraq to its people. As a candidate, I promised that I would end this war, and that is what I am doing as President. We will have all of our combat troops out of Iraq by the end of this August. We will support the Iraqi Government as they hold elections, and we will continue to partner with the Iraqi people to promote regional peace and prosperity. But make no mistake: This war is ending, and all of our troops are coming home. Tonight all of our men and women in uniform, in Iraq, in Afghanistan, and around the world, they have to know that we--that they have our respect, our gratitude, our full support. And just as they must have the resources they need in war, we all have a responsibility to support them when they come home. That's why we made the largest increase in investments for veterans in decades last year. That's why we're building a 21st-century VA. And that's why Michelle has joined with Jill Biden to forge a national commitment to support military families. Now, even as we prosecute two wars, we're also confronting perhaps the greatest danger to the American people, the threat of nuclear weapons. I've embraced the vision of John F. Kennedy and Ronald Reagan through a strategy that reverses the spread of these weapons and seeks a world without them. To reduce our stockpiles and launchers, while ensuring our deterrent, the United States and Russia are completing negotiations on the farthest reaching arms control treaty in nearly two decades. And at April's Nuclear Security Summit, we will bring 44 nations together here in Washington, DC, behind a clear goal: securing all vulnerable nuclear materials around the world in 4 years so that they never fall into the hands of terrorists. Now, these diplomatic efforts have also strengthened our hand in dealing with those nations that insist on violating international agreements in pursuit of nuclear weapons. That's why North Korea now faces increased isolation and stronger sanctions, sanctions that are being vigorously enforced. That's why the international community is more united and the Islamic Republic of Iran is more isolated. And as Iran's leaders continue to ignore their obligations, there should be no doubt: They too will face growing consequences. That is a promise.
