Imagine if some tyrant took control of Canada, made an alliance with China, and then China installed missiles in Canada on the American border. America wouldn't tolerate this and would take military action to prevent it. This is basically the scenario that Russia was facing with Ukraine where the leader clearly wants to join NATO and the America has refused to promise that this won't happen. This forced Putin to preemptively act to prevent this from happening. I personally see Russia as the last refuge of western civilization. The West has become an evil satanic globalist cesspool that threatens all decency in the world. So I am extremely grateful to Putin for taking decisive action to defend Russia.
