Civilians across Eastern Europe protested and helped bring about the fall of communism based on their belief that the West would bring a superior way of life, government, and economy to their countries.
For whatever reason, it all failed. Assuming slightly higher oil prices than we have now, life under the USSR would likely be better.
Some particularly egregious things the West / Wall Street did:
1. No plan to absorb the massive amount of laid off secret police and military members. These ppl would turn to organized crime very quickly. Same mistake made in Iraq in 2003.
2. Giving Russia garbage loans they were in no position to pay back and had to be repaid in dollars only. An absolute disaster that Goldman Sachs was mostly responsible for.
3. EU was completely unprepared, for what has now become, the greatest migration in human history. The best and brightest left Eastern Europe in droves, causing massive brain drain that helped usher in the collapse of regime after regime.
4. Sending a CIA team to Moscow in 1996 to directly override the wishes of the Russian people. In defense, the USA was worried in a reasonable way that the communist party would win in a landslide at the polls. But regardless that should have been their choice.
5. Not focusing on Afghanistan after leaving in the late 1980's, letting jihadism further spread to Chechyna and the devastating war from 1994-1996 their. Causes terrorism on a 9/11 scale in Moscow, hundreds of Russian tanks destroyed, just insanity.
