By the same metric every war in the world is China's problem because they manufacture most of the shit required to live on this blasted planet (and indeed, do bad stuff with). I just read an article about how the Ukrainian military just can't have enough of Xi's murder drones. Do they know they're actually supporting Hamas? Should someone tell them? Anyway, US bombs blowing up yemeni school buses is not the US's fault sweaty, learn some realpolitik.
