The issue is that there was NO support for Prigo. He was totally isolated. Not one single person in a military or political position of power came to his side as he had hoped. Every single actual source of power in the country (and outside of it) backed Putin.

Compare this to 1991 when the communists attempted a coup in the soviet union to (correctly) prevent its eventual dissolution. They had the Gang of Eight which included:

Gennady Yanayev (1937–2010), Vice President
Valentin Pavlov (1937–2003), Premier
Boris Pugo (1937–1991), Interior Minister
Dmitry Yazov (1924–2020), Defense Minister and Marshal of the Soviet Union
Vladimir Kryuchkov (1924–2007), Chairman of the KGB
Oleg Baklanov (1932–2021), First Deputy Chairman of the Defense Council of the USSR
Vasily Starodubtsev (1931–2011), Chairman of the Peasants' Union of the USSR
Alexander Tizyakov (1926–2019), President of the Association of State Enterprises

This was a REAL and powerful coup attempt with real political and military support. A true split in the country.

They failed, and no further attempt would occur afterwards, it strengthened the state and the opposition forces that sought to end socialism in the country and bring about the economic hell of Shock Therapy.

You can not possibly argue that this mutiny (calling it a coup compared to past failures is laughable), by one man with literally zero allies, which ended in a single day has done anything other than strengthen the state by showing everyone how there is no political or military division. Not to mention Wagner is being disbanded as well so that only brings that chapter to a close.

You people need to get more realistic.
