I agree with others, blaming the invasion on the expansion of NATO is victim blaming. Russia was and is a credible threat to these nations. Otherwise they would not have felt the need to join NATO and get its protection. Historically Russia has treated these eastern european nations as its property to lord over. This is true now, was true during the Soviet era and was true in the imperial era as well. This is an old and deep rooted notion of what Russia considers its sphere of influence and vassal states. It goes so far that almost as soon as they came to power the Soviets set about bringing the former vassal states of imperial Russia back under their control. They invaded Poland in 1918. Of course it should go without saying they also joined Nazi Germany in conquering Poland in 1939 and after WW2 quickly moved to bring all of eastern europe fully under their control. Finland managed to remain independent after two costly wars with them. Many of these nations see NATO membership as essential to their survival. If anything the last week proved them right. If you don't join NATO then Russia will eventually try to conquer you again.
