Palestinian Triangle of Who is Fighting Who?

Hamas militia arrested seven members of Army of Islam which kidnapped British journalist Alan Johnson. Hamas claimed they were agents of Fatah which is now governing the West Bank after being driven out of Gaza. Fatah claims the Army of Islam works with Hamas. The Army of Islam says it is the true representative of the Palestinian people. In the midst of the Palestinian tragedy one senses a comic opera in which everyone is fighting everyone. Shouldn’t they all be focusing on the main issue — achieving an independent Palestine?
