I don't think anyone disputed that Russia committed a war crime against Ukraine by invading. However literally no Western country is saying the same thing about Israel and the US's completely unprovoked attack on Iran.
Not to mention Israel's ongoing genocide in Gaza which the West are doing nothing to stop even though they are obliged to act under the Genocide Convention.
I agree we are just micturating in the wind but US corporate media is taken with a delusional bloodlust and it's important to respond with facts in the face of manufactured consent for bombing a country that is no threat to the US.
