Hamas officials voiced support for leaving the Gaza government. This appears the result of international pressure on Fatah to keep Hamas out of the PA government.
In the result, Fatah will be able to claim a moderate government, though it will be heavily influenced by Hamas. Hamas will be able to bring its people into the government as independents. And most importantly, Hamas will concentrate on its “resistance enterprise”, i.e. terrorist activity which it has almost ceased while ruling Gaza.
