This blog asserts that nuclear weapons can best be understood as technological instruments that reflect engineering talent; essentially IQ.

In 1956 the United States could have desroyed both Russia and China using nuclear weapons delivered by bombers. China and Russia could not have responded. Today the United States could destroy Russia and China in less than an hour, but China and Russia could also destroy the United States. What happened in 50 years was more detrimental to the United States than to Russia and China. There is a reason for that. Russian and Chinese engineers have matched what American engineers can do.
The best Chinese and Russian engineers do very well on IQ tests.
