China is almost wholly dependent upon U.S. citizens for their economic growth and well-being, so the idea that China is itching to start a hot war with the U.S. is rather laughable, at least for the near future.

Remember, it's always bad business to kill your customers.

I think by far the more credible threat, of course, is from terrorists (foreign and perhaps even domestic, as horrific as that seems) and do hope that the superpowers of the world come up with some defense systems that are able to mitigate such attacks.

But to be honest...this new military-sponsored "killer robot" world we are barreling headlong into gives shudders to most sane, peace-loving citizens, no?
