Story from the 80's. Islamists took Soviet diplomate hostage in Lebanon. KGB sent leaders of the organization photo's of their home, wife and kids. Diplomate released.
Might be the same incident. But I have heard alot of corroborating evidence that the Soviets are absolute masters at non-lethal torture.
Things quite a bit more effective than putting panties on some dudes head.
Such a solution sounds harsh, but it did work, didn't it? We may have to make similar choices in the years ahead.
