Anyone who believes that Russia invaded Ukraine due to NATO is just spouting Russian propaganda. And sounding foolish the whole damn time.
Vladimir Putin gives us no reason to believe that he fears a NATO invasion. If Russian leaders feared such an eventuality, the last thing they would have done would have been to undertake a full-scale invasion of Ukraine, as they did in 2022. That amounts to sacrificing most of their army inside a country that is not a NATO member. If Russians feared a NATO invasion, they would not have created a situation in which Finland and Sweden join NATO, which they have done.
Pro tip: If you want to understand global geopolitics, start with not being an unpaid Russian shill. That’s not enough of course, but it’s a good starting place.
