The Palestinians are not on the verge of a civil war. They're already embroiled in one: Since the beginning of this week, two judges and the three children of a senior security officer were murdered in the Gaza Strip. Fatah blames Hamas and members of the Popular Resistance Committees loyal to Hamas. Yet the Fatah is also doing its part.
Armed security forces who are Fatah loyalists are running wild through Gaza's streets and firing in every direction as they demand to receive their salaries, while in the West Bank we see the occasional violent clashes between the two sides, not to mention the wholesale abductions. For the time being, the number of casualties is relatively low, yet the trend of escalation is clear and consistent.
What's going on today in the Palestinian street is very reminiscent of the process that took place in Iraq after it was taken over by the Americans in 2003. There too the civil war started with sporadic violence and terror acts against the Americans and between Shiites and Sunnis. These acts became more frequent until they spiraled out of control.
