As far as I'm concerned, while we could bicker about whether Russia or the West has been more insanely stupid in its part in the escalating spiral of provocation in recent years, it would be quibbling over details.
The point that matters is that all of the governments in question are behaving like fools, and need to be brought under control or replaced with saner minds before the same pattern of stupidity that we saw a hundred years ago leads to the same results - and this time around, both sides have nuclear weapons.
Don't know who you are but I'll happy if citizens of the West will be under an impression that nuclear weapons will never be used. For many reasons.
As part of bringing Russia closer, the West decided to shred Russia of its defense interests inherited from the Soviet Union. There was a systematic attack by the West on Russia's interests in Central Asia, Georgia, Syria, and now Ukraine. You can only bait the bear for so long until it bites you back.
But he isn't "biting back" at the West. He's biting on the bones of thousands of civilians (of all nationalities) killed in Ukraine. And hundreds of his own soldiers, sent illegally (by Russia's own laws) to fight in a war beyond its borders.
