No, they aren't. You could have said "some are more or less useful to specific causes," but the way you worded it is quite troubling at best. Rwandan lives are no less important than Ukrainian ones, and vice versa.
What you're saying here seems to imply that if genocide were carried out in my country tomorrow, our lives would be less important as long as the perpetrators didn't pose a threat to NATO. I'm not sure whether you see how concerning that sounds to someone from the same region as Rwanda.
So it's all about geopolitics, after all? Going by what you said, it sounds like human rights, democracy, and the other mantras the US touts aren't exactly the main motive for aiding people in other countries against war crimes and mass murder.
