It's not moving to goalposts to acknowledge that the USSR beat us to space and that a large part of their collapse was due directly to the influence of the US.
You go on to state that Russia beat the US into space (which is a non-sequitur), and later expand that "The USSR, had it not had to fight a cold war against the US, could very well have been a much better system not just for space flight, but for a way to structure and run society in general."
When challenged by alentist, who asked "why did the USSR and its satellite states have to systematically mass murder people who wanted to leave this wonderful society?" you countered with "If it was such a bad way of doing things, why did the US actively go out of it's way to sabotage it" which is moving the goalposts, and starts to slide into whattaboutism.
Specifically you claimed that the USSR "could very well have been" a better way to structure a society, and alentist provided strong evidence that it was not - people were murdered when they tried to leave. Instead of trying to prove your point you deflected, and shifted the goalposts from "this could very well have been a good system" to "the US didn't like it therefore it couldn't have been bad".
Still, it would have been better not to restrict emigration. That was not humane, and betrayed an antiquated view of how the world works.
