So, in summary, my computer and I working together now believe that because for the foreseeable future China and the US will be powerful enough to inflict unacceptable harm on each other the prospect of mutually assured destruction should prevent military war, though there almost certainly will be dangerous skirmishes. I expect this to be true unless some unexpected technological breakthrough, like dramatic advances in quantum computing, gives one of these powers such an asymmetrical advantage that mutually assured destruction would cease to exist.
