How does it make sense to remove an option, to tell your enemy before you go into a conflict, that you will not exercise whatever options are necessary in order to achieve victory?

The question is not whether you would like to be president or not. The question is: Do you think you can win and do you want to run? And none of those are clear to me.

Well, I don't think it is amnesty to start with. Second of all, what do you want to do with them? That is the question in response. And third of all, it is a tough path to citizenship. You have to pay back taxes. You've got to learn English. You've got to have a clear record. You've got to get to the back of the line behind other people who have come here legally or waiting legally. So, i just reject that.

We can't go on forever with 11 million people living in this country in the shadows in an illegal status. We cannot forever have children who were born here - who were brought here by their parents when they were small children to live in the shadows, as well...

I think we also ought to prepare the American public, by way of informing them, that Saddam Hussein has these weapons, continues to attempt to improve their capability, and would not be reluctant to export them to other countries. So he presents a clear and present danger.

I think where [Donald Trump] loses most hawkish republicans is when he talking about how much he likes [Vladimir] Putin. That should make any person who believe in the American exceptionalism, incredibly uncomfortable.
