I would guess they are taking precautions against an attack from one of the ‘stan countries, or the middle east. Seems prudent to me, the genie is out of the bottle, and there is a non-trivial probability of non-state actor detonating a nuke in my lifetime. Non-proliferation can’t work perfectly, forever.
I do not think that the stan” countries pose a threat. The reason why many of the stan’ countries are under Moscow’s sphere of influence. The Middle East is not a threat because most of them get their weapons from Moscow.
I don’t think so. I think they are planning for a first strike against a weakened and demoralized West.
