I think that the real import of the article is that if you believe these analysts, then the Chinese apparently have an intent to engage in nuclear war, and perhaps they think that these shelters will work. It really says nothing about whether they actually will.
Personally, I think both of the conclusions are nutso. More likely, if it means anything, it simply means that they've figured out that like Jung-Il, they can manipulate the American thought processes and cause histeria over here by doing meaningless things like this.
Perhaps...
But the Chinese have a billion people and little regard for life. The only thing that matters to the Chinese government is perpetuation of the Moaist state...no matter the cost.
The Chinese, just like chinese drivers in this country, and unlike Russians, have no common sense. I am afraind they could legitamize a nuclear first strike against, perhaps, a carrier battle group while they engage Taiwan...they'd expect a retaliation in kind from us.
A nuke war with China could play out.
Why would they want to eliminate their best customers?
