> It's good to remember Ukraine never possessed operational control of them [0], Ukraine had full control, and an operational arsenal for a few years. There was no such thing as a PAL on Soviet nuclear weapons. Ukraine had a fully functioning nuclear force for these few years. I will give no credibility to claims of Western think tanks who can't tell apart a tank from an apc.
This goes against my knowledge and documentation available on the matter. Any sources on these claims? Thank you. >By early 1994 the only barrier to Ukraine's ability to exercise full operational control over the nuclear weapons on missiles and bombers deployed on its soil was its inability to circumvent Russian permissive action links (PALs). (from "Pulling Back from the Nuclear Brink" by Barry R. Schneider)
Just too much of fiction writers working in these think tanks to pump grants, and research funding.
Even today, go and lookup a number of articles on something very trivial, say, "Russian general military doctrine," and your will get absolutely random, and bizarre assortment of opinions not agreeing on anything, despite that the official doctrine document in Russian is not secret at all, and is easily googleable on the internet.
A lot of them are just regurgitating each other's data without any original input, or validation. A broken telephone effect ensures.
