It is just as true to say

that the "deciding factor" in any dispute among any number of people is might.

A political philosophy expresses (implicitly or explicitly) a value judgement about right and wrong.

Contra your Armageddon example, above, I have already pointed out numerous times that a political philosophy is a statement of general principles which serve as a heuristic guide to action in the real world, and that any political philosophy can be reduced to absurdity by a particular set of circumstances (whether contrived as in your example, or actually occurring).

You are still dancing.
