If China, Iran, and Russia are smart they'll follow the Taliban's blueprint of repopulation. Once the eternal simp is destroyed the world will be able to move on. Hell, China could just do governmenr mandated gfs/marriages and embrace the shitty manga before Japan does. They do that and eliminate WR and Divorce you'd see some marked changes in population pretty soon. Their only problem would be feeding those mouths, but they probably could by just requesting Russia to stop feeding Africa too.
