In Libya, armed militias have filled a void left by a revolution that felled a dictator. In Syria, a popular uprising has morphed into a civil war that has left more than 100,000 dead and provided a haven for Islamic extremists. In Tunisia, increasingly bitter political divisions have delayed the drafting of a new constitution.
And now in Egypt, often considered the trendsetter of the Arab world, the army and security forces, after having toppled the elected Islamist president, have killed hundreds of his supporters, declared a state of emergency and worsened a deep polarization.
The post revolutionary period in Tunisia has had its rocky bits, there has been
some political violence.But it hasn't had anything like the scale of violence or the scope of chaos witnessed in Libya, Syria and Egypt. Tunisia, unlike the others, has a functioning democratic government. For all its flaws, the country has a semblance of normalcy and stability that the other three do not have.
