America cannot do this alone.

I know that for more than two centuries, we have strived - at great cost and great sacrifice - to form a more perfect union.

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

This is the moment when we must come together to save this planet.

People of the world - look at Berlin!

I know that I don't look like the Americans who've previously spoken in this great city.

But my country and yours have a stake in seeing that NATO's first mission beyond Europe's borders is a success. For the people of Afghanistan and for our shared security, the work must be done. America can't do this alone.

Despite past differences, this is the moment when the world should support the millions of Iraqis who seek to rebuild their lives, even as we pass responsibility to the Iraqi government and finally bring this war to a close.

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

This is the moment when we must defeat terror and dry up the well of extremism that supports it. This threat is real and we cannot shrink from our responsibility to combat it.

I will take no options off the table in dealing with this potential Iranian threat.

America must always stand up for Israel's right to defend itself.

I will lower the health care costs of this country enough to bring down premiums by $2,500 for the typical family.

It is true that some of the tribal leaders as well as the local governor in Anbar expressed concerns about a potential precipitous drawdown of U.S.

I think that his concern has to do with wanting to retain as much flexibility as possible.

I believe that the situation in Iraq is more secure than it was a year and a half ago. I think that the definition of success depends on how you look at it.

The message we heard from Iraq's leaders is that they're ready to do more and they want to take more responsibility for their country.
