Is that NATO currently in the room with you?
Russian aggression reinforced the need for a buffer state - before it wasn't obvious, now it is. NATO is intending to force Russia to leave Ukraine and they are willing to play a very long game bc it's a buffer state in play, not a NATO state.
The end result of this strategy is either Russia breaks or the war escalates.
Russia-NATO relations were pretty good, even heading (slowly) towards such membership under Putin in 2000.
Unfortunately, Putin didn't like GWB leaving the ABM treaty, and did like having the old USSR back, so aggression and all else as you say.
Which was a surprise at the time, and left some convinced it was a UN rather than NATO operation.
But thanks for playing.
