The Russians and rogue actors, including ISIS - this is a serious part of the 21st century security challenge that we face.

I think the lesson's learned are that we have to have to have a strategy to get and a strategy to get out. Which means, that you create a stable situation.

To honor the people that died, we need to stop the Iran agreement, for sure, because the Iranian mullahs have their blood on their hands, and we need to take out ISIS with every tool at our disposal.

We now have a lack of readiness that is quite scary. We have planes that were - that Harry Truman inaugurated, the B-52. We have - the Navy has been gutted and decimated. The readiness of the Marines is way down.

It's a complex relationship when your dad happened to be president and you are president and then you have all the amateur psychology that goes on when people try to speculate about motivations.

Every weapon system has been gutted.

The job of a president is to identify, distinguish between the two. Make sure the people know that we view it as a threat that we're - because people are scared and they're legitimately so. Take action accordingly. And then you're going to lessen people's fears on the day-to-day activities. We can't be paralyzed in place. And that's where we are today.
