I think many people seem to have missed the fact that recognition of a palestinian state is not absolute but conditioned on a negotiated settlement.
Everyone would like the palestinians to have a state and stop the violence against Israel, the problem is the negotiated settlement. Nations that would like to recognize a palestine want to get Abbas back to the table and for hamas to be disarmed. Taking hamas off the terror list is a gesture to help them to take that step. If Hamas and Abbas don't or won't talk turkey with Israel they can be put back on the terror list just as quickly.
The EU is trying to open the door for them. Will they enter with an olive leaf or an AK47?
If the PA declare a state on land they now control that will be the end to Israel leaving the rest of the WB in any way. Palestine will be a group of inland islands that will need visas and authorized ID to travel from one area to the other by passing through Israel.
If they talk they will likely get a solid piece of land with some sort of land trade leaving Jerusalem with Israel open to tourists and Israeli muslims and limited access from non-Israeli muslims on Fridays and holy days. Muslims in the WB and G would have to attend their own mosques and apply for visas to visit the mount a few times a year. Israel would control how many foreigners can visit at any one time to prevent any hostile action against Israel.
Jerusalem is not part of the required pilgrimage my muslims. They might wish to visit but they are not required to do so my Islam.
If palestine take unilateral action they will be surrounded by forces that could crush them on at a time if they fire on Israel. No hiding behind "international resolutions". They will be a state of islands in a sea of Israel waging war and can be cut off trapped in a jail of their own making.
If palestinians want a real state they will have to come with the intent of being flexible and truly willing to work with the Jewish Israeli state as a permanent fact, and cooperative neighbor.
If they squander their chance the rest of the world might not be will to truly recognize them ever again. They can come hat in hand or sword in hand, but they will get more with only the hat and a will to do the realistic best for their people.
Time for dreaming to end and to wake to a new year and a new outlook.
