Nothing you guys love more than declaring victory while running away

When did Russia invade Belarus, exactly? I can't find anything about that at all, did you just make that one up entirely?

So imperialism only exists at a certain scale?

The bigger scale a country does imperialism on, the bigger a concern it is and the more attention should be paid to it, yes. Otherwise, you're just cherry picking.

The overwhelming majority of imperialism is done by the US, so trying to downplay that and shift the focus is no different from cherry picking some crime done by an immigrant while ignoring the general trend that immigrants tend to commit fewer crimes. This isn't a difficult concept, lol.

I was under the impression that it had more to do with a country’s foreign policy objectives

Objectives? That's pretty subjective, isn't it? It depends entirely on the country's motivations. So you could potentially look at the decades-long military occupation and plundering of Afghanistan and say, "Well, our objective was to build democracy so it wasn't imperialism."

You could assign all sorts of nasty motivations to a country like the DPRK, based on your own presumptions, and be like, "Well, they would try to take over the world even more than the US if they had the capability to, so they're more imperialist than the US," even though the US controls half the globe. That's completely absurd.

Did you know that at the school of the Americas agents of the United States, including FBI CIA and border patrol actually, taught fascist kill squads that systematically raping nuns is a good way to cow a populace. Just wanted to put into context what you're defending for some bizarre reason.
