What is happening is directly pointing out that this was is NOT different. That this war is ALSO unjustified.
In war, the aggressors are the problem. Period. And lending support to the aggressed is not the same as supporting war.
It would work, simply letting Russia finish a genocide against Ukraine or Israel finish a genocide against Palestine. The conflict would certainly be resolved that way. But if you think it is an acceptable outcome, you value peace too highly.
