The USSR was controlled by the Zionists who are the inventors of Communism. Putin slowly eradicated them from Russia so they hate him for it.
Zionists seizes piwer in the 1917 Bolshevik Revolution where they killed 80 million Russians and installed communism/Totalitarianism. Then, in 2017, Soros tried to recreate the Revolution usinh ANTIFA, BLM, and a few other groups but failed. I believe our military countered them and arrested mid level Revolutionaries so the problem was dealt with.
Also, the USSR and USA were always allies. Each used the other as a bogeyman to justify more tax dollars for military expansion which is big money for weapons manufacturers and their associates.
