He literally just said that ISIS has people on US soil during his coverage of that poor journalist, but they don't know how radicalized they are... This is the closest story I could find to match what I watched on CNN. http://www.cnn.com/2014/08/20/world/meast/journalist-beheadings/
The UK is reporting that the man behind the beheading of Foley is a Brit. " A well educated,Intelligent but highly committed member of the extremist terror group. " There are around 500 such committed Brits many of whom travelled to Syria to fight with and for Isis.Some appear also highly educated { medical school }. Osama bin Laden was highly educated and committed.However OBL had plenty of funds being born into wealth by a Billionaire father in Saudia Arabia. One could argue ... follow the money.Isis WAS funded and trained. The Mujahideen was what inspired OBL in Afghanistan after his being ousted from first Saudia Arabia and then the Sudan. He had no country and therefore decided to dedicate his life in hiding to " Allah " as newly proclaimed leader.When OBL joined the Mujahideen forces in Pakistan they were used to fight against the Soviet Union in Afghanistan.Scuttlebut has it that our own government was complicit in helping to fund and re-establish a Mujahideen force in order to topple the hardened and battle ready Soviet forces who fought diligently for years.
