"We are opposed around the world by a monolithic and ruthless conspiracy that relies on covert means for expanding its sphere of influence, on infiltration rather than invasion, on subversion instead of elections, on intimidation instead of free choice, on guerillas by night instead of armies by day. It is a system that has conscripted vast human and material resources into the building of a tightly knit, highly efficient machine that combines military, diplomatic, intelligence, economic, scientific, and political operations." President John F. Kennedy
