What goes around comes around. Hamas made life difficult for Fatah when it was responsible for the PA. Now Fatah is determined to repay the favor. Hamas asks it to end the practice of displaying weapons in public. Fatah says no.

Will Hamas go where Fatah feared to trade and enforce its demand for a PA monopoly of power? Abbas ran on the platform of one authority, one gun but Hamas said no. Now Fatah says no. Then, as now, the losers are going to be the Palestinian people. Then, as now, the world will blame Israel for the mendacity of the Palestinian leadership.
