The Second Amendment was designed explicitly to protect weapons that would be useful in a military context.

I think President's candidates need shock collars or something.

Let's go back to the beginning of the Obama administration, when Hillary Clinton and Barack Obama led NATO in toppling the government in Libya. They did it because they wanted to promote democracy. A number of Republicans supported them. Well, the result is, Libya is now a terrorist war zone run by jihadists.

We should be breaking down barriers, not building walls.

I don't think we should be engaged in nation-building. It's not our job to turn foreign nations into democratic utopias, to try to turn Iraq into Switzerland. It is the military's job to hunt down and kill our enemies, to kill ISIS before they murder American citizens and they wage jihad.

Twenty years from now if there is some obscure trivial pursuits question, I am confident I will be the answer.

I do believe, in the long term, we will either get back to the principles that built America or we lose this country. And I'm an optimist.
