The problem is that your 'solution' is worse than the problem. It'll begin with a bloody war, which will create plenty of grievance against the invading forces, followed by an occupation which will be all able what is good for the invading forces, usually at the expense of the locals. The 'good' way it ends is the invaders draw down and leave in defeat, nothing good having been accomplished. The bad way it ends is the invaders deciding they want to get something for all the money they spent, and them going into full colonisation mode.
