It is possible the oligarchy can come from the political left. If they feel less violence is likely if they assume control than if they let the other side assume control, that is a "good" rationale to move in this direction.
And this decision could depend on who is throwing who in prison.
A lot depends on the secret meetings between the senior military leaders and back-room players of both political parties.
My mission is to bring a different kind of democracy to the world, where we won't need these secret meetings.
