Not much direct experience here, but it seems likely to me both sides see the other as "stone walls" simultaneously.

My comment would be: Where is the unity of command? At some point there has to be a big dog to settle these disputes. Imagine a military campaign with no joint force commander. Each component is off doing it's own thing, using its own vision to win the war. ISTM that's what is happening between other agencies, NGO's and the military - there's not higher authority that can make them play nice and work together using a coordinated strategy.
