Here is my attempt at a thrid world imagi-nation campaign. It has been basically a solo campaign that I've been working on since 2009 (I think):

The page gives a list of blog post links about building up to the campaign, and then AARs and back story.
I don't really address the rules directly, but mention methods, and things considered in the game from time to time. Somewhere in there is a post entitled, "Behind the Scene…" that goes into some of the things that are taken into account and can happen.
My approach to the strategic campaign rules, is that I simply create tables to randomize events as their potential occurs, resulting in what I sometimes refer to as the "Fate Tables". There is a running "unrest"value to the general public, possible mutiny, assassination of leaders, etc. with chances of any of these going up and down as each given country experiences success and setback.
I don't maintain an intelligence system, so much as create a give a chance of intelligence successes as plans/ideas occur, and then give corresponding modifiers to the dice rolls on the fate tables.
It is kind of open ended, and probably not quite what you are looking for, but the closest that I can share.
