Yes, we are the imperialists. We could have shown Russia that we weren’t harmful by not piling up our weapons along its border. But chose not to, because we wanted this war.
We could have talked to Russia and made it clear not respecting the Ukraine border would result in war, but we chose to pile up our weapons instead.
We are the imperialists.
