So the fighting in Gaza has culminated in Hamas victory and total control of the Gaza Strip. The Palestinian state which was always geographically split finds itself politically split as well with Ftah retaining control of the West Bank. This Guardian article provides some interesting insight into the Hamas fighting and victory, claiming that Hamas was targetting key elements of Fatah "one group of Fatah agents who were following the Zionist agenda", not Fatah as a whole and that some Fatah members provided assistance. Furthermore according to some people including civilians, Hamas won so decisively because they were motivated and disciplined while many Fatah fighters were simply criminal thugs who took advantage of their status and uniform for money and power. This also meant Hamas fighters were ruthless and much better soldiers.
The article has Hamas announcing that they still recognise Palestinian President (and Fatah leader) Abbas as President though he has formed a new Cabinet, dropping all Hamas members.
The most obvious outcome for now, would be that Abbas and Fatah would hardly want to reconcile with Hamas. However taking into account past proliferation of Palestinian peace deals and the sobering fact that refusal to deal with Hamas would cause a definite breakup of Gaza and West Bank, it is a bit likely that the 2 sides might negotiate.
Whether one believes Hamas' account and feels this fighting was for the better of the Gaza Palestine or that this is a ruinous occasion, it is apparent that the rule of the gun.
