North Korea and China have proposed what sounds like a pretty sensible option that North Korea should end its development of nuclear weapons, the US should stop carrying out hostile military maneuvers on the North Korean border. The US immediately rejected it. Modernization program is a very clear example of how security doesn't matter. There is no gain in security but massive overkill of the adversary's deterrent capacity. The only consequence of it is to elicit the likelihood of a preemptive attack. And a preemptive attack leads to a nuclear winter world.
