So Hamas probably will reject a peace plan that has been globally accepted including the PA as it refused to disarm. Hasan fighters would rather carry on basically a suicidal guerrilla campaign rather than lay down arms for a peace so many right minded people desperately want.
Don't Hamas realise they will lose Gaza and effectively their 'fighting' force will be groups of jihadis who engage in occasional small arms fire that in all likelihood result in their deaths? What sort of mind set does this group have where they are willing to prolong a vicious war with no thought to the people they are meant to stand for?
Hamas hope is grounded only in the West being weak and applying more pressure on Israel and conceding to the terrorist Hamas. If the West more fully backs Israel now then Hamas may lose that one deranged hope and possibly their doomed war may end.
