@Kathy: Sometimes longer. 🙂 I am the only one who has the ability to moderate comments on this site. If it’s the weekend and it’s your first comment, a comment might be held in moderation all weekend. On weekdays, it depends. In this case, it’s an extremely busy time right now here with us launching about 4 new things within the month and me setting them all up. Usually I check comments first thing in the morning and then irregularly throughout the day. However, I was awake until about 5am this morning (PST) working on those aforementioned new things and so comments were checked a little late as a bit of sleep was needed. 🙂
One prominent feature of the nuclear arms race, especially following the massed deployment of nuclear ICBMs due to the flawed assumption that the manned bomber was fatally vulnerable to surface to air missiles, was the concept of deterrence via assured destruction, later, mutually assured destruction or "MAD." The idea was that the Western bloc would not attack the Eastern bloc or vice versa, because both sides had more than enough nuclear weapons to reduce each other out of existence and to make the entire planet uninhabitable. Therefore, launching an attack on either party would be suicidal and so neither would attempt it. With increasing numbers and accuracy of delivery systems, particularly in the closing stages of the Cold War, the possibility of a first strike doctrine weakened the deterrence theory. A first strike would aim to degrade the enemy's nuclear forces to such an extent that the retaliatory response would involve "acceptable" losses.
