In an explosive new book, CIA contractor James Mitchell talks of his time as an interrogator of al Qaeda leaders and alleges that their plan was not to destroy the U.S. militarily but to use lax immigration laws, weak politicians and procreation to take the nation down from the inside.

The Washington Post published excerpts from Mitchell's "Enhanced Interrogation":

[Khalid Sheikh Mohammed] 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."

President Barack Obama has been criticized by many conservatives for allowing increased immigration from countries that are suspected of terrorist activities without proper vetting. Conservatives have also looked askance at Obama's desire to provide refuge for a vast influx of Syrian citizens fleeing turmoil in that country. Indeed, President-elect Donald Trump made reversing these decisions part of his campaign platform.

In another telling conversation, KSM noted that one strategy to undo the U.S. internally was to rely on the weakness and predictability of her political and media class. From the book:

KSM said, "Your own government will turn on you. Your leaders will turn on you. They will turn on you to save themselves. It will play out in the media and strengthen the hearts of the brothers. It will recruit more to Allah's cause because the press coverage will make the U.S. look weak and divided."
