Tunisia

Long War: Tunisia has not yet seated a functioning caretaker government. The Tunisian Army (TA) is getting increasingly involved but so are various powerful trade unions, muddying the water. Protests continue unabated in front of the Prime Minister's office and demands are becoming increasingly incoherent. And protests are spreading to other Arab countries. The Gulf states are beginning to issue checks to citizens to stop the contagion effect from Tunisia's revolution.
Violent protests are erupting in Egypt. The Egyptian protesters want money or state jobs, not democracy. In Lebanon, Hezbollah is forming a new government and placing itself in the center, not a positive development for democracy in the region. And a Hezbollah led Lebanon increases the chance of war with Israel. War or the threat of war is not propitious for fledgling democracies.
What needs to happen going forward in Tunisia is for the TA to either fully back the existing caretaker government or form a new government by force. Tunisia's primary Islamic political party claims that it is committed to helping establish a Turkish style democracy. And in Egypt the Muslim Brotherhood is saying pretty much the same thing.
If Tunisia does transform into a Turkish style democracy, then it will be possible although extremely difficult for the US to build democracy in the region. If Tunisia goes sideways, then all hell will break loose.
