Madison was the driving force in ensuring that the US framework was designed to promote Good Governance perceptions. THAT is great COIN. Military efforts to deal with insurgency merely dealing with the mess after government has failed in a primary function of serving its populace in a manner that promotes perceptions of Legitimacy, Justice, Respect and Hope.

The key is not to mimic the US constitution, but rather to understand why it works and to mold appropriate constructs to produce similar effects when developing constitutions elsewhere. Every culture is unique, and different things will contribute to these universal perceptions accordingly.
