To elaborate:

Following World War II, Frank Wisner helped found the Office of Policy Coordination. Officially, its mission was refugee assistance and working with the International Red Cross. Its actual mission involved covert actions against the Soviet Union. Wisner was a wily, charming, Southern aristocrat who was forever changed when he witnessed the brutal Soviet occupation of Romania. His office invested heavily in psychological warfare, which was still a relatively new concept. Ideas that came from the office included delivering American toiletries across the Iron Curtain (to demonstrate superior Western standards of comfort) and airdropping enormous condoms labeled “Medium” onto the Soviets, to demoralize them against an anatomically superior American army. (Sadly, this plan was never carried out.)
