I'm an American actually. It's pretty ironic that you're saying that Russia is obsessed with imperial domination when you're comparing it to the United States which has over 800 military bases spread across dozens of countries all around the world, is literally occupying multiple countries with tens of thousands of troops right now including Japan, Germany and Australia, has overthrown dozens of regimes it didn't like all around the world and has completely destroyed two entire countries on the opposite side of the planet in the last two decades. If that's not imperial hegemony, I'm not sure what is.

Also, the West never explicitly invited Ukraine into NATO but they repeatedly refused to say the door was closed for two decades.
