The Associated Press is reporting the U.S. military is now admitting that the Iraqi resistance is far larger than it had previously estimated. Some military officials said the resistance now has so much popular support among Iraqis that it can no longer be militarily defeated. For months the U.S. has put the size of the Iraqi resistance at about 5,000 members. Now estimates are closer to 20,000. And the resistance appears to be almost entirely Iraqi-based. USA Today is reporting just 2 percent of the nearly 6,000 detainees in Iraq are suspected of being foreign fighters.
