"It ends up creating a parallel economy, so the indigenous public sector has no support." As a result, the local economy is neglected, and when the big international projects are finished, it is in tatters. That sparks a volatile combination of poverty and resentment which can reignite war.
Quick political fixes, such as "transferring the formal trappings of power" to a hastily installed post-conflict government also fail, says Patrick.
