You surely don't REALLY think that McCarthyism was no more than a Hollywood witch-hunt? If so, your understanding of American social history is pitifully inadequate. Google (for example) "Operation Northwood" - the CIA files are now declassified and avaiable for perusal even on theor own website. Plans to kill American citizens in staged "terrorist" attacks... and blame it on Cuba, to provide an excuse to invade. At least the Russians are honest about their own history.
Yes american authorities were gripped by paranoia and acted secretly and murderously. However I think it's a bit like comparing the freemasons with the mafia. Neither are partcularly to be recomended but one is infinitely more deadly. (the answer is the mafia by the way in case you thought....)
I repeat: "Google (for example) "Operation Northwood" - the CIA files are now declassified and avaiable for perusal even on theor own website. Plans to kill American citizens in staged "terrorist" attacks... and blame it on Cuba, to provide an excuseto invade." Only a (coincidental) change of government brought in a new SecDef, who axed the plan. Point is.. NOBODY EVER GOT PUNISHED. It just got swept under the carpet, and things carried on as before. The most effectively imprisoned people are those who (despite any amount of evidence to the contrary) firmly believe that they're "Free". They never even attempt to escape.
The point surely is that this was a plan that was never enacted. During Stalin's reign literally millions of soviet citizens were tortured and killed. Every country has dozens of these sort of schemes lined up, fortunately they rarely actually happen. In stalinist russia the nightmare came true.
The REASON that it was "never enacted" however (and pay attention: this is IMPORTANT) wasn't because of some kind of imaginary superiority of the US way of life. It's simply that Robert McNamara (JFK's incoming SecDef) didn't agree with the plan. No outrage about wicked behaviour... just the usual whitewash. Note that the USSR's constitution of 1936 made it (on paper) the free-est country in the world. Problem for Russians was that the paper was worthless. Russia was (and remains) NOT a country "governed by the rule of law". Neither for that matter is the USA. The BIG difference being... Americans are self-deluded into believing the opposite, and amazingly willing to ignore anything that provides evidence to the contrary.
I have read the details of this plan and I agree it's outrageous. It was drawn up by the armed forces chiefs of staff however. Chiefs of staff tend to do this sort of thing constantly, calling civilian deaths collateral damage etc. In the uk there were various plans for an armed takeover of the govt in the late 60s early 70s by the army chiefs. Kennedy responded to this crackpot scheme by sacking the main architect, and taking action to limit cia operations in the US. I'm no apologist for America but I still don't see a reign of terror comparable to stalin's. I don't remember Captured US troops in the 2nd world war being imprisoned or shot by their own country on their release as were many soviet ex-prisoners. Some nasty plans against a 20 year reign of terror? No contest!
