I take ISIS at its word. When they said, in their words, 'We'll use and exploit the refugee crisis to infiltrate the West,' that concerns me.

We didn't take the words of Vladimir Lenin seriously until Communism spread across the globe. And unfortunately, the president didn't take the words of groups like ISIS seriously until they established a sweeping self-proclaimed Islamic Caliphate.

A nation ringed by walls will only imprison itself.

I am extremely concerned that Syrian and ISIS recruiters can use the Internet at lightning speeds to recruit followers in the United States with thousands of followers in the United States and then activate them to do whatever they want to do.

A Trump administration will take on this fight and send a clear message to the Islamist terrorists: you may have fired the first shot, but rest assured, America will fire the last.

Home is where you feel more welcome, more secure, have more rights, where you are loved. This place can be any place even away from what you would normally call home.
