ISIS is the greatest threat.

The threat is real, and it comes from the Internet. This is a new generation of terrorist. This is not Bin Laden in caves with couriers anymore. This is what the new threat of terrorism looks like.

I think Syria is now the training ground for the world... These rebel forces are more of a threat than anything.

I know there's a lot of discussion about building a 2000-mile wall. I think we need to complete the Secure Fencing Act, but we need greater technology and aviation aspects down on the Southwest border so we can see the threat from the sky. Until you can see it, you don't know where it's coming from and how to correctly stop it.

We do a very good job at fixing broken bodies but not such a great job at healing broken minds with our returning veterans.

We need to look at how we can better fortify our force protection at military installations. But also, how can we deal with these mental health issues with our returning veterans? And our suicide rate in the military is twice as high as the average population.
