Sorry I resent the post above accidentally. Anyway, warsprite, you said:
"All above were nation states with a clear chain of command for one. None thought that they would be rewarded with heaven for killing non believers."
Well, leaving aside some of the wackier elements of the South African National Party in the 70's and 80's with decision making power both civil and military, I will concede your second point. Although assuredly both Stalin and Mao thought that their efforts to liquidate the bourgeoisie and deviationists from their own interpretation of Marxist-Leninism would be praised and revered by future generations. Your first point is both false and inapplicable, however. The chain of command was completely meaningless during the Cultural Revolution, when it basically just took a denunciation from an ambitious underling to end or paralyze any bureaucrat's career. Stalin was busily firing up the mechanisms of purge when he died, and the only military figures with even a modicum of safety from the NKVD and the stukaches planted throughout the Red Army were Zhukov and Konev. France wound up having a near civil war over DeGaulle's withdrawal from Algeria. South Africa in the 80's was a snake pit of secret cliques and factions that bore little relation to any organizational chart. So, there have been many instances where the CoC has been dubious at best with a nuclear power in crisis.
Additionally, India was and remains about the farthest thing from a nation state imaginable. Same with the Soviet Union. I'll give you the PRC because of Han dominance within the culture, but clearly, not all nuclear powers in crisis have been nation states.
Now, on to the part where your point is more or less moot. The Pakistan Taliban is more or less an expression of Pashtun nationalism. Assuming, for a moment, that the Pashtuns can beat the Panjabis and take control of Pakistan, do you think the control over the nuclear arsenal is going to pass to any but the most reliable elements within the Pashtun-dominated government? I mean, the nuclear arsenal of Pakistan would be the greatest guarantee of the continued independance of a Pashtun-dominated state. You really think they're going to use that for anything other than guaranteeing their own control over Pakistan? Of course, this leaves aside any issues of sabotage that the essentially exclusively Panjabi Strategic Arms Division might commit when faced with the prospect of losing control of their nuclear warheads to a bunch of what Panjabis universally perceive as a tribe of goat fuckers.
