What is opposing a war?

People call themselves war opponents when they oppose invading Vietnam, which is good.

People also call themselves war opponents when they oppose Ukraine defending itself, which is bad. They support Russia invading Ukraine. They support wars except the ones when the US is invading.

It reads a lot different if you're familiar with Gourevitch's writing, especially on the Rwandan genocide. "We Wish to Inform you that Tomorrow we Will be Killed with our Families." Read it if you haven't already.

A leftist is someone who opposes every war except for the ones the fascists might win.
