There is one thing we could do …..but wont , however its a legitimate aspect of warfare ……….now that the human genome has been unraveled , it would not be hard to produce several genetic plagues that only affect asians , if the onset time was long enough , they would be screwed hard with the disease already infecting major swaths of the population , by the time its recognized as a disease . All other races would be immune because its a genetically engineered disease . Delivery is not a problem considering how easy global travel is . Good luck finding a cure ………….just sayin

I do believe that the major powers have already used Africa as a small scale testing ground for biological warfare , it has a large population , its 3rd world , so containment is not a problem , and nobody cares what happens over there .
