Oh, so Reagan caused the collapse of the world oil market. HAHAHA.
Solidarnosc would not have come off the ground had Pope John Paul II not endorsed it by telling Poles they had nothing to fear. It was after John Paul’s visit that millions joined Solidarnosc.
Cash had no impact on Solidarnosc’s success. Poland was an impetus because, unlike other parts of the USSR, once Solidarnosc was formed, workers united with the intelligentsia. That had never happened anywhere else in the Soviet bloc. Ever. Soviet dissidents were largely failed communists. Only a couple (Bukovsky, for one) were not trying to be “better communists”. They held the working class in contempt. And that is why such a movement was never formed in the USSR. The first person in the USSR to “speak” normally to the working man was Yeltsin.
As for the rest, nobody knew what was “vital” to the Soviet economy. This is a nice theory, but you know what? All those analytics in the CIA and military intelligence were taken completely by surprise by the collapse of the USSR.
What, exactly, does that tell you about American intelligence operations? I can’t blame them - totalitarian states are virtually impossible to infiltrate.
