I didn't say that. In fact I acknowledged that the US attacked it. But the USSR also worked to undermine capitalist regimes. So what? You're the one that isn't being serious because you don't have an answer for the fact the Soviet Union was a walking contradiction. It claimed to be a workers socialist government yet in praxis it was state capitalism with an authoritarian government. That contradiction is what brought it down. But yeah it's easier to just blame America and keep the socialist movement from learning and adapting.
