Not even trying to be hateful about it but jeets are hugely over populated and are flagrantly damaging the environment of their own country, and data seems to suggest the air pollution could be getting dragged all over the planet. Nuke would be interesting scientifically because I wonder if the vaporizing sun ball effect would clean all the smog away instantly or not. The real answer though is staging events that destabilize the food supply.
