If we look past the North Korean missile program, has the U.S. opened Pandora's box by using malware to affect another country's missile launch?
We used to talk about Stuxnet infecting Iran's underground nuclear computer systems which destabilized their centrifuges, but now we're talking about malware affecting the "left of launch" of a missile. If this is the future of stopping a potential nuclear attack from another country then is everything that used to be stable about the nuclear order now in disarray due to the "cyber age"? During the Cold War, The U.S. and the USSR knew where each other's missile were located and generally shied away from operations within the other's command and control systems for the most part.
Are we not inviting other major powers to play around in our nuclear systems? It's one thing to try and stop the North Koreans from launching a missile at California, but if the Chinese, the Russians, and the U.S. are inside each other's command and control centers, does this not undermine the mutually assured destruction doctrine? It could help make a country be so sure of its capabilities that it would be willing take a bet and never suffer any proportional retaliation.
