I'm gonna try to follow your logic in good faith. If both Russia and the US should be held accountable for their crimes, then who should actually hold them accountable?

NATO is the international arm of the US military and it has committed war crimes over its entire decades of existence, some of the most recent ones in Iraq, Libya, and Syria. If the US is to be held equally accountable for their actions as the RF should be, then all NATO operations should be held under the same scrutiny.

So by this logic how can you support a NATO in it's actions in Ukraine. Before Russia invaded, NATO was supported the bombing of the Donbass and the destruction of that region. If the US and NATO has a history of destabilizing regions through warfare for the benefit of the US, how can any of their actions be justified?
