A worse outcome than a genocide of one people.
You can understand, perhaps, how some people- or likely many, if we're talking those suffering the conditions of Gaza right now- would disagree, and act accordingly, though.
Personally I would also disagree- Gaza, and Palestine at large, survives for now, but should the total eradication of Gazans, akin to what was done across the eastern seaboard of the US, near its endgoal, I fully and utterly hope that war, to whatever extent necessary (world war included) begins to end the genocide, even if it risks the species and biosphere altogether.
I would rather humanity dies on its feet, than on its knees. To me, while I can accept, understand, and support biding one's time (when and if it is beneficial- as it is for now, for China and perhaps for Russia alike), ultimately, in the whole picture, I think there is nothing more abhorrent, more inhumane, than turning the other cheek permanently and unilaterally- as even famous pacifists like Gandhi spoke against (the "emasculation of a whole race," or in this case, the whole of humanity, the global south, and the working classes). And the imperialists in particular are undeniably the enemies of humanity, a very real and well-recognized threat to the biosphere in their own right. If it is not put down, sooner or later capitalism, imperialism in particular, will likely kill us all the same.
