KT McFarland decided to re-enter the national security arena after 9/11. She had stepped down as the highest-ranking woman at the Pentagon in the Reagan administration to raise a family.

So why did McFarland, national security contributor for Fox News Channel, come back? In an on-camera interview with The Daily Signal, she tells me America’s long war against radical Islam will be “the challenge for the rest of my life.”

McFarland also talks about the refugee and migrant invasion taking place in Europe. It’s not just an economic crisis, she says; it’s potentially a major terrorist threat.

“You’ve got a real powder keg,” she says.
