Ok, but why do you keep mentioning China, I said I wasn't worried about China. I'm worried about the crazy folks (e.g. NK) with limited launch capability. China is pretty stable.
Because the overall context here is China, the potential for war with China, and the devastation that would result. I want to be clear that our defenses would not prevent that.
Really, you think "In any all-out war between two nuclear nations there will be no winner, just two losers" in a discussion about war with China wasn't talking about China?
I provided a counter-example that is much more likely and frankly a lot more worrisome. Plus, I specifically mention what I was worried about. Comments on HN expand out from the topic all the time, and I was pretty specific in my response.

The interceptors are expensive, so there aren't very many. That's why it can defend against a country like North Korea but not China.
