That, unlike other proposed solutions, would certainly work. The problem is that these political fracture points are there because of opposing interests between different groups in society. This can be easily solved in more authoritarian government structures by simply choosing a winner and a loser, but in democracy not so much.

And while I don't have any doubt in my mind that there are foreign entities working to exploit these fracture points, I am very skeptical that they are the main cause of problems here. We have seen such fracture points arise and cause political strife up to the point of civil wars many times throughout history without such foreign instigation.
