Bridge Over Troubled Water

I'm working on an additional part of the a.i., that rules the purchase of weapons by the Arab nations. I'll add also an arms race feature: if no-one starts to purchase other units then the other players will do the same, but as soon as one starts a buildup of forces his neighbors will emulate him. The decision to start an arms race on part of the a.i. will depend on the aggressiveness of the leader and the strategic situation, so a weaker nation will try to balance the strength of his neighbors.
Then I'll start working on the informative text, a painful job that I'll try to do as quickly as I can.
