I smell sarcasm, but still, you're not that wrong. The motivation absolutely matters - US Imperialism is much softer, even in it's war crimes, than Russian Imperialism that comes with genocide bundled. In the former case where it hurts is that they try to paint a rosy picture (freedom and democracy etc.) while committing war crimes / invading left and right for business interests, and that hypocrisy is very annoying. At the same time when the Russians invade, they're brutal, war crimes are part of their process. I'd take the former over the latter any day, even ideally neither should be a thing in the 2020s.
