Perhaps you misunderstood my comment. I basically said that I thought having a maximum length of service was a good idea, but I didn't think two terms was the right target. Perhaps three terms would be a better target. The reason I think three terms is better is that you want the leader to have to face up to their own mistakes. It strikes me that with one or two terms there's still a tendency to blame your predecessors for the state of the country rather than accepting responsibility for the cock ups.
