4. Moscow's perception of NATO as threatening should not be surprising much less incomprehensible. NATO was created in opposition to Moscow and served as the military counter-balance to the Soviet alliance for 40+ years. NATO expansion was both an instance and cause of the shared failure to integrate Russia with the post-Cold War European order. Regarding the structural character of NATO, as analyst Edward Luttwak has pointed out:

 "NATO is not a security-talking shop but a veritable military force, complete with a hierarchy of operational war headquarters, intelligence and planning staffs, a joint surveillance force of AWACS aircraft, an air defense network with radar from Norway to Turkey and elaborate logistic facilities... In other words, NATO is a fighting force, temporarily at peace." Edward N. Luttwak, oped, "A Look at Expanding NATO,” Washington Post, 06 Jul 1997.

Since the end of the Cold War, NATO or its leading members have conducted multiple regime-change efforts using both non-military and military, covert and open means. For Russia (or any nation), the close proximity of a powerful strategic competitor would constitute a potential "threat in being." At minimum, close proximity would give the alliance greater leverage over Moscow. To compensate for NATO's eventual spread to Ukraine, Russia would have to substantially increase surveillance and defenses along a ~2300-km border. It would still be vulnerable to increased cross-border surveillance, espionage, and covert action. And, of course, there's no easy way to compensate for the loss of 1,000-km of defensive depth.

Recognizing these realities in no way justifies Moscow's recent actions or its behavior in general. Recognition only serves to illuminate the predictable paths of Russian policy.

Dmitry Stefanovich of the Primakov Institute of World Economy and International Relations in Moscow also speculated that the alert was "primarily about increasing the readiness of automated battle management systems to ensure the delivery of retaliatory launches under any scenario." Pavel Podvig of the United Nations Institute for Disarmament Research similarly speculated that the Russian "nuclear command and control system received what is known as a preliminary command."

To indicate a higher state of Russian strategic force readiness “land- and rail-based mobile missile systems can be dispersed, missile-armed submarines in port can be sent out to sea, and bombers can be loaded with nuclear weapons.

131. There have been dozens of nuclear weapon-related accidents since the 1945 as well as a handful of publicly-known incidents of mistaken near-use due to faulty perception of attack. A high percentage of these false warnings occured during conflict crises - in 1956 during the Suez Crisis, 1973 during the Arab-Israeli October War, and most critically during the Cuban Missile Crisis when a Soviet submarine nearly launched a nuclear torpedo, US radar operators separately mistakenly reported to the US air defense command that a missile attack was underway, and a US F-102 fighter armed only with nuclear air-to-air missiles rushed to protect a U-2 that had wandered into Soviet air space. It should not be surprising that mistaken perceptions or rash action cluster around crisis periods.
