china has more males than females. That means a lot of angry chinamen.
1.3 billion and counting only .3 billion in the us (people).
They can kill and replace every single living person with a chinese and china would still be the most populus country in the world. China has been trying to kill us all with lead and tainted food as it is.
China can't mobilize and their leadership is fractionated. we wouldn't bother dropping troops on them when we can sit off their shores in our ships and subs and choke off their oil. and yes, we'd go nuclear at any sign of losing the war. many today, including france still lament the fact that we didn't nuke vietnam in 1964. that mistake won't happen again.
