"Overthrew" is doing an awful lot of heavy lifting there. Bottom line, Putin doesn't get to decide the fate of a sovereign nation. There was never a treaty forbidding NATO eastward expansion, and previous Russian presidents stated that NATO was not a threat to Russia. In its entire history, NATO has never launched an offensive against a non-NATO country.
Russia, on the other hand, has launched multiple offensive operations since Putin came to power (Chechnya, Georgia, Crimea), as well as provided military assistance to rebel groups in Abkhazia and Ukraine. It is logical that former Soviet republics might have an interest in seeking the protection of NATO. The majority of Ukraine citizens were against joining NATO prior to the 2014, but public sentiment has changed quickly since the 2014 annexation of Crimea.
You are drinking Putin propaganda straight from the hose.
Russia insists that there was an agreement not to expand Nato eastwards after the end of the USSR. History begs to differ.
