Some in the West have long argued that because of the lack of a viable liberal alternative, supporting authoritarian regimes in Arab countries is the only political choice against the Islamists. Now, in Tunisia, as people flood into the streets demanding democracy, we see that this is not the case. It was not the case in Iran in 1979 either, but the West was so invested in the Shah that it failed to strongly back the liberal opposition. We don't have to repeat that error today.
