They are not going to declare independence from the whole Palestine, very unlikely so. Even though they are separated from the West Bank, they have a lot of supporters there. People in the West Bank even voted in majority for them in 2006. The only reason they can’t rule the West Bank is because Fatah has greater number of henchmen there and Fatah got the support from Israel and the West to cling to power.

Currently if you study the maps, their forces is moving towards the West Bank, at one time just 10km from it. And they have been making many pleas in the social media to invite those in the west bank to join them. So, they’ve been quite a number of incidence of attack in the area around west bank, indicating that they are gaining more support.

So the trend now is for them to unite instead of separated into different entity.
