For the sake of saving civilisation, it is imperative that China be abolished, for we cannot suffer the existence of such dastardly, sociopathic, polluting fiends. After doing a lot of calculations, I've figured out the best plan for nuking China.
Our first step is to nuke all the port cities, this helps us twofold as (1) no Chinks can escape, thus they are stuck in the chaos, and (2) no aid can come to China. These nuclear strikes will directly kill 237,554,451 Chinks, excluding people outside of the cities’ boundaries, while using 8.55% of the US nuclear arsenal.
The remaining US nuclear arsenal would be sufficient to kill 1,038,559.9 square km worth of Chinks. While this is insufficient to flatten the rest of China’s area, we can still kill every Chink INDIRECTLY without even using the entire nuclear arsenal.
During the havoc caused by the ports’ destruction, the internal supply chains will be mobilised to ensure everyone gets food and water. What we do now is (1) contaminate the water and soil, (2) nuke the Three Gorges dam, and (3) destroy infrastructure.
The destruction of this dam will kill 400 million Chinks through flooding, and if that weren’t good enough, hundreds of millions of shitskins in various Asian countries depend on water flowing from China, and will also perish.
China has 1.2 million square km of arable land, which is more than we can nuke, however China is not self-sufficient in food and relies on the imports we’ve made impossible. Furthermore, even without radiation, Chinese food is already poisonous as fuck even at the crop level, with 10% of their farmland being contaminated by heavy metals. Only about 533,000 square km’s of Chinese land is high quality pasture, so we can easily delete their agriculture and have plenty to spare for ruining waters and infrastructure – in fact, contaminating the water will destroy most of the pastures anyway.
