Why the hell do I have to keep updating my apps on my iPhone all the time and why you don't fix that?

I'm not surprised that Governor Dean would oppose [the $87 billion to fund Iraq reconstruction].... I've lost confidence that he has any understanding of the national security responsibilities of a President... [b]ecause I don't believe that he has any understanding of the international role that the United States has to play in the world. I think it's a kind of a pseudo-isolationism that appeals to the base of the caucus voters. I do not believe that particularly in the case of Iraq that Governor Dean has any fundamental understanding of what's at stake here.

There is always an element of realpolitik that has to be present in the conduct of any nation's national security affairs. At the same time, we have to also have a balance between realpolitik and Wilsonian principles of freedom and democracy and human rights. And maintaining that balance is the greatest challenge that we in the West, including the Federal Republic of Germany, have to face because it's many times a very difficult decision-making process.

My greatest fear is the Iranians acquire a nuclear weapon and give it to a terrorist organization. And there is a real threat of them doing that.

I am fully prepared to be commander in chief... I don't need on-the-job training.

I guarantee you, as president of the United States, I know how to heal the wounds of war, I know how to deal with our adversaries, and I know how to deal with our friends.

I campaigned in 2012 all over this country for months: 'Repeal and replace Obamacare.' That was not the mandate of the voters. If they wanted to repeal Obamacare, the 2012 election would have been probably significantly different.
