9 out of 10 Americans would likely perish.

ISIS attacks in Brussels, California and Paris may be just the beginning of an unprecedented plot to bring America to its knees by targeting our nation's scandalously vulnerable electric grid, warn officials at the Pentagon and FBI.

Why? Because terrorist groups like ISIS realize they can't beat us with brute military force on the conventional battlefield. We're way too strong for that.

But when the electric grid fails, it will be like watching America have a heart attack right before your eyes.

It's like when the heart stops pumping... everything shuts down and the patient flat lines.

Our great country would be crippled in a matter of minutes, without our enemies having to fire a single bullet.

It's a frightening idea... and worst of all, it may already have begun to unfold:

ISIS terrorists are already inside our country. Former CIA official Dr. Peter Pry warns, "There is an imminent threat from ISIS to the national electric grid and not just to a single U.S. city." Dr. Pry says that attacks on just 9 of the nation's 55,000 electrical substations could result in nationwide blackouts for up to 18 months.

The government is woefully unprepared. It seems like the government has been fixated on taking more & more away from people who worked hard to earn it, while doing virtually nothing to secure our nation's infrastructure. They've ignored dire warnings from experts about the grid's vulnerability to physical, electromagnetic pulse (EMP) and cyber-attack by ISIS and other terrorist groups.

"Our death toll would be staggering" reports FOXNews. We've all been fine when the power goes out for a few hours and even days, but an extended blackout would be devastating. Frank Gaffney, founder of the Center for Security Policy predicts that "... should the power go out and stay out for over a year, 9 out of 10 Americans would likely perish."

Imagine a blackout lasting not days, but weeks or months. Your life would be frozen in time right at the moment the power fails. Lights all over the country would go out, throwing people into total darkness.

Without access to a generator, your fridge, electric range and microwave would be dead. All the food in your fridge and freezer would spoil.

Your well couldn't pump any fresh water into your house. And even if you don't have a well, a total grid failure means no fresh water to drink, cook, or clean with.

You wouldn't be able to operate your radio or TV, or charge your cell phone, so you'd feel isolated and cut off from your friends and family.

Sadly, this is NOT science fiction or some crazy doomsday theory...

Veteran news anchor Ted Koppel just wrote a book called Lights Out that details this exact scenario. And CENTCOM General Lloyd Austin says, "It's not a question of if, it's a question of when."
