When Al Qaeda launched the 9/11 terror attacks, it was radical Islam’s most deadly strike in their war against the West.

But what if murder and violence wasn’t how Al Qaeda believed they could ultimately defeat America?

A new book reveals the shocking details of the terror group’s ultimate strategy to take down Western civilization.

When U.S forces captured Khalid Sheikh Mohammed (KSM) – the architect of the 9/11 attacks – he was interrogated for information on Al Qaeda’s plans.

What he revealed was chilling.

In the book, Enhanced Interrogation, author and CIA contractor James Mitchell reveals the details of what KSM divulged to interrogators.

He claimed that while death and destruction were a major part of Al Qaeda’s plans to defeat American and the West, their real strategy was attacking from within.

Radical Islamic terrorists would use immigration and reproduction to fill the United States with a Muslim population to overtake the country.

The Washington Examiner reports:

Snippets obtained by Secrets from the book set for release next Tuesday from Crown Forum show that Muslim terror groups had a much bigger plan to crush America than just through attacks like 9/11.

Instead, the plan is to fill the country with like-minded Muslims through the country’s easy immigration laws and by having babies, and then using the U.S. legal and welfare system to turn the country into a system like Iran.

Consider this passage in the book, Enhanced Interrogation: Inside the Minds and Motives of the Islamic Terrorists Trying to Destroy America, where KSM reveals the plan to Mitchell:

“It would be nice,” he said, if al Qaeda or like-minded Islamists could bring America to its knees with catastrophic attacks, but that was unlikely to happen; “not practical” is the wording he used. From his perspective, the long war for Islamic domination wasn’t going to be won in the streets with bombs and bullets and bloodshed. No, it would be won in the minds of the American people.

He said the terror attacks were good, but the “practical” way to defeat America was through immigration and by outbreeding non-Muslims. He said jihadi-minded brothers would immigrate into the United States, taking advantage of the welfare system to support themselves while they spread their jihadi message. They will wrap themselves in America’s rights and laws for protection, ratchet up acceptance of Sharia law, and then, only when they were strong enough, rise up and violently impose Sharia from within. He said the brothers would relentlessly continue their attacks and the American people eventually would become so tired, so frightened, and so weary of war that they would just want it to end.

“Eventually,” KSM said, “America will expose her neck to us for slaughter.”

Europe is already feeling the strains of increased Muslim migration.

In 1990, Muslims were four percent of Europe’s population.

In 2010, they made up six percent.

By 2030, they are expected to grow to eight percent of the continent’s total population.

Some countries in Europe are already at these levels.

In 2010, Muslims made up 10 percent of Russia’s population, seven-and-a-half percent of France, and just under five percent in Germany.

The most obvious example of Muslim’s migration changing the political landscape is in London.

In 2011, the Office of National Statistics reported that Muslims were 12.4% of London’s population.

In 2015, they helped elect Sadiq Kahn, a Muslim with past ties to extremist groups.

Obama’s globalist open borders policies opened the United States to a similar invasion.

He took in 10,000 Syrian refugees in 2016.

And the Senate Subcommittee on Immigration and National Affairs reported Obama handed out one million green cards to Muslims during his eight years in office.

These policies were on the ballot on November 8th, and the American people soundly rejected them by electing Donald Trump as President.
