When the state has access to nukes and the populace doesn't, how can this statement not technically be true? It seems like the ability literally wipe cities off the face of the earth means that you have the permanent upper hand, in terms of power.

Further, what you call "cooperation" I think would largely would be a lack of organization. The ability to organize can grant immense power, and when people talk about the power of large crowds like this I think there's usually an unstated assumption of "if they were to spontaneously act in great--or at least adequate--coordination." I don't think it's fair to assess power in terms of something like a body count, and to ignore the power granted by organization.
