Also, we can't ignore the US-backed Ukrainian coup/revolution in 2014[2] which then resulted in the invasion of Crimea. Nor can we ignore that after the democratically elected government in Ukraine was removed via that coup/revolution, that the US handpicked the post-coup leadership in Ukraine and helped rewrite the Constitution to put NATO membership back on the table, knowing this would antagonize Russia.[3]
Should we not consider all of these things? Russia is clearly being the aggressor now that they have decided to invade Ukraine, but that didn't happen in a vacuum. Our actions in the West are what has led to this, either intentionally or though incompetence. Ignoring everything that happened before February 24th is ignorant.
