China is an interesting (and thoroughly messed up) place ... but I suspect its future is brighter (and I don't mean massive nuclear explosions) than we may think. Christianity is thriving there, despite persecution and being forced underground ... The Romans tried to destroy Christianity ... and ended up becoming Christian. I wouldn't be too surprised to see something similar happen in China over the next couple of generations.
I remain more worried about China...
But, I would be interested to know if the high birthrate in Islamic countries dilutes/minimizes the radical strain.
