Israeli wall

Question: When is a fence not a fence?

Answer: When it is 8.5 meters long and made from concrete.

I grew up in the world of terraced dwellings in the UK where every house has a fence on the neighbouring side. I know the difference between a fence and a wall. What I see in Israel (occupied Palestine) is NOT a fence but a prison just like the world had created in Germany to separate the Capitalist West and Communist East.
