The map below shows the distances.

Between the West Bank border and the sea, at Tel-Aviv-Yafo, where about half of all Israeli Jews live, there are only 11 miles (18km). If you live in a large city, its diamater is easily larger than this. It is a distance that can easily be jogged by someone in good physical condition.

After Annapolis, there will be no space in which to retreat, if the Israelis are attacked from the West Bank, no space for military meneuvers. Israelis will be sitting ducks.

 The map below shows the elevations.

Annapolis will give PLO/Fatah strategic high ground, wheras the Israelis will be trapped in a lowland.
