I do think that Cobra has an ideology.
They are meritocratic facists with a military bent. That is they belive the strong should rule and one should always obey the ones above you in the chain of command because they are better than you. This is liked to their belief that democracy is evil and corrupt and that the world is best served with a strong supreme leader.
The militaristic bent takes form of their incredible desire to uniform everything and everybody LoL.
Their meritocratic idiology is tainted with their love of ruthlessness or their view of ruthlessness being a mental quality rather than a lack of mental quality.
Its Heinelens vision of the perfect political system but with more realistic characterization of the individuals within the organization.
Off course their ideology is vaugely described by Larry Hama as he focused on the individuals personal journey.
