Lebanon
Prior
Late in 2004 we obtained Lebanese data alleged to be much more accurate that what we had first used. This inflicted considerable computational misery on us. Scenarios were literally all over the map: in some Lebanon actually prospered. Politically, in some forecasts Lebanon became truly independent but collapsed economically; in others it remained under foreign control; and in a third set it was effectively divided into various combinations of Syrian, Hezbollah and Israeli zones and so on.
We regret to report that mathematically at least nothing has changed very much.
