Below is a map of the West Bank (in French, but it's easily read).
The red line — the Wall. Note how most of it runs well inside Palestinian territory.
Yellow squares — permanent checkpoints (there are far far more 'temporary checkpoints')
Black triangles — settlements started after Israel agreed to cease new settlement activity.
Orange — the glaring truth-teller — land barred to Palestinians. Note especially the Jordan River Valley, a crucial source of water. Israel gets approximately 40% of its fresh water from the West Bank. Be assured that Israel has no intention at all of ever leaving the Jordan River valley.
Orange lines — "Jewish-only" roads. Sound like apartheid?
