Marcus Luttrell, the former Navy SEAL who was the subject of the book and movie “Lone Survivor,” has a chilling warning for Islamic extremists planning to attack American citizens at home:

Self-defense is what the Second Amendment is all about.

“I know you’re watching, so pay attention,” he begins in a new promotional spot for the National Rifle Association. “You hate my freedom, my religion and my country … Don’t ever confuse me for my politicians or my media. I am an American, free born and free bred … My freedom is more powerful than anything you can possibly do. I will say what I think, worship according to my beliefs, and raise my children how I see fit.”

“And I defend it all with the Second Amendment to the Constitution of the United States,” he added. “I cower to no one, because I am the National Rifle Association of America.”

The ad comes at an opportune time — on the week of the 14th anniversary of the 9/11 attacks that killed almost 3,000 Americans.

The terrorists are well aware of the date’s significance also.

Al-Malahem Media, the media branch of Al-Qaida in the Arabian Peninsula, released the latest issue of its English-language magazine “Inspire” calling upon “lone wolf” assassinations of notable business people in the United States.

Targets include brothers David and Charles Koch, Bill Gates, Warren Buffet, Michael Bloomberg and Sam Walton.

The cover depicts a hooded gunman facing photos of some of the targets listed in its feature story, “Assassination Operations,” according to the Middle East Media Research Institute, or MEMRI.

Luttrell appeared on Fox & Friends Thursday to promote the ad and discuss AQAP’s hit list with co-host Brian Kilmeade.

“I thought it was kind of funny that they were target out businessmen and billionaires,” he said, telling the terrorists, “You might want to start a little further down the food chain,” and suggested they start with him.
