Did he ever try that on radical islamists who think death in defying us would get them god-status and eternity with 79 eternal virgins? islamic fanatics are not the same as nazis and japs. Most germans were not nazis, and even though most japs were fanatical, they are not as bad as the islamic terrorists of today. I still contend, based on information from first hand sources, that people like the terrorists are much more likely to talk if pressed, than if they're given three hots and a cot at the Marriot.
Sherwood Moran didn't interrogate radical Islamists, so we don't have any record of that.
I wonder if his methods would work, though. I haven't heard of anyone else using them.
