when did he drop those? today?
your question / musing at the end.
Yes, it's pretty much what they do.
CIA docs explain how the military itel was operating with thousands of Nazis / Soviets at the end of WW2. For allowing this to happen (setting it up) Allen Dulles was rewarded.
From his perch he and his Bush friends staffed many positions through the back door (no evidence except some letters which suggest that that is the case)
I believe foreigners were sent to US specifically before ww2 to staff important positions which would allow all of this to happen and it has just grown ever since.
