One thing I agree with Donald Trump on is, there's something going on in the Muslim world.

I know Donald Trump as a very adaptive person. In my nearly three and a half decades of being in the military, I've had maybe one, maybe two guys that I've worked for that were that adaptive in combat. He adapts to the great challenges, with his own sort of street smarts and his instincts.

We have a problem with radical Islamism and I actually think that we could work together with Russia against this enemy. They have a worse problem than America does.

When you look back, history is not going to be kind to these last 16 years from 2000 to 2016.

Obama's decision to leave, to not sustain the victory that resulted after eight years of fighting, from 2003 to 2011 in Iraq, was another incredibly stupid decision. It was totally based on politics, not based on any notion of national security. It's a nightmare for our national security. And then you have the Libya intervention.

Egypt is going to be, potentially, a failed state if we don't help them.

I think that [Obama] sees the military actually as something that is more dangerous to the world. I think that he looks at the United States military and sees it as a threatening application around the world than actually as a useful tool.
