I found this interesting:  The trail of training guerilla warfare and subversive tactics may have started in Germany at the end of World War II, but it advanced into Egypt, South America, and even into the United States after the war with Skorzeny as a paid consultant. Eventually it spread to Al Qaeda through the efforts of Skorzeny, his subordinates and Yasser Arafat. Skorzeny was, in effect, a guerilla warfare consultant for hire, to whomever wanted his new tactical and creative ideas, including the United States Special Forces. https://intpolicydigest.org/2016/07/18/otto-skorzeny-the-nazi-who-influenced-isis/   Regarding your last statement, did Uncle Trump make sure they didn't see anything they shouldn't?
