Mikhail Gorbachev has died

The United States didn't do enough to help Russia transition to democracy in the 1990s. There was no "Marshall Plan" after the Cold War like there was after World War II. This was a huge mistake, and we see the consequences now, with Russia having turned back toward totalitarianism and imperialism. Sadly, it seems that Gorbachev's efforts were mostly for naught. But it was courageous at the time to open up the Soviet Union to glasnost and perestroika.

Of course Yeltsin was a big part of the problem too.

Your comment makes it sounds like you believe the U.S. had the power to decide whether or not Russia would turn into a kleptocracy or not. Maybe I'm misinterpreting you, but if I'm not, I'm skeptical. Marshall plan notwithstanding, I would give credit to the people and government of Japan for their post-war success: it could easily have gone another direction, and the U.S. couldn't have stopped that from happening. Likewise, the people of Russia and their government are ultimately the ones with agency in their case. I don't think the U.S. should take on the burden of developing other countries; going down that road has been a bad idea more often than not.

I suggest you read more about the post war occupation of Japan. The U.S. put its thumb heavily on the scale forcing Japan to accept democratization throughout. Unusual for the U.S. this included pushing economic democracy by supporting Japan's very successful land redistribution scheme.

More than a thumb. The Constitution of Japan was written by Americans. America stomped on the scale, and that time it seems to have worked.

isn't it cultural ? japanese seems to be ok struggling under american control and keep reaching higher. People say US money made Japan thrive but so many time throwing money at a large problem fails.. I think the population was just more mentally compatible.

Or maybe the post soviet Russia was dealt a bad hand. Hard to know (just like here, you can find infinite streams of contradictory arguments)

Hard to say. I suspect the horrific bombing of Japanese cities probably had something to do with their willingness to submit. Leaving their Emperor intact as a figurehead probably helped a lot. Perhaps American willingness to help Japan rebuild immediately after such a bitter war also played a role.

There were probably innumerable factors that went into it. But there are a lot of differences between that situation and the fall of the Soviet Union.
