Indeed. I could see it as a first world nation today if it plays it's cards right
Well, lets not get ahead of ourselves. Ba'athist control of Lebanon will see most of the banks based in Lebanon still flee to Bahrain or another Gulf state. While Iraq's oil will help, the country will be large, fractious and full of ethnic conflict, and its state-controlled economy will be relatively inefficient. Now, if Jadid puts a lot of effort into reforming the economy, moving more towards a market socialist model, Syria will have a chance of being a real power, especially by Mideast standards. However, if/when the USSR collapses, its not going to be pretty. Imagine Yugoslavia in the desert, with its neighbours encouraging the violence as opposed to at least pretending to try to halt it.
After Yom-Kippur, I see just extrem appeasment by the Maronites prevent the Civil war.
Agreed, post-Yom Kippur War, the real factors behind the civil war were already in place. Without the Maronites giving up most to all of their power and, say, giving the Palestinians all citizenship, there would still be a civil war.
