It would be great to demand an end to the war.
However, the way to demand an end to the war is to demand that Russia leaves Ukrainian territory.
If they will not voluntarily leave Ukrainian territory, then Ukraine will seek to remove them by force.
It's unclear what you're trying to say with "how many countries have we bombed". Are you trying to say that the cruel and unjust actions of the US justify the cruel and unjust actions of Russia? I demanded that the US leave Afghanistan for my whole adult life. I now demand that Russia leave Ukraine. Anyone who actually cares about ending the war would be demanding the same. Surely you understand that Ukrainian capitulation would only lead to more war as Russia's inhumane expansion tactics would be validated.
