A while back I read a piece about political stability not being all it seems. It made the case that looks can be deceiving, and illustrated it something like this. Since 1945 Italy has had some 40 changes of prime minister. Saudi Arabia has had 6 rulers in the same period. North Korea has had 3. By that metric, Italy appears pretty unstable, while the other two look like oases of calm. But which keeps you up at night? For all the Machiavellian twists and turns in Italian politics, the political process has a way to reset the compression of the spring, to take out some of the tension every few years to stop it from popping, as the Italians turf out the incumbent and vote for a change. North Korea and Saudi Arabia on the other hand don’t have the mechanism, and need more and more pressure to keep it in place. The force underneath keeps on building though, the eventual reaction getting bigger. But that’s statistics for you – measured that way you get an answer on stability, but it’s probably the wrong one.
