Exactly my dilemma too.
I'm sure will see some democratic countries in middle east and north Africa.
Will they be successful and long lasting? I don't know.
I'm sure some will be overrun by Islamic extremists. I'm worrying that this might happen quickly and world will have to wrestle with next Iran and Afghanistan, this time closer to Europe.
At the moment the worst situation is in Libya. We are looking at civil war. One tribe in East and Kadafi tribe in west. The battle will be fierce for the control of oil fields. The only hope is that they split the control and the country in half, and fighting will stop soon.
