Van Creveld: “Never” is too much of a word. Nothing lasts forever. But history proves that walls work. The Roman wall – the Limus(?) – worked for hundreds of years... the Great Chinese Wall worked, not forever, but for hundreds of years... the wall in Korea has been working for fity years... the wall between Turks and Greeks in Cyprus is working.... the Berlin Wall worked beautifully.... Unfortunately, the Israeli army insists against all military logic on being present on both sides of the wall. We could formally finish the problem at least in Gaza, in 48 hours, by getting out and building a proper wall. And then of course, if anybody tries to climb over the wall we kill him.
This military genius was completely wrong about the effectiveness of a wall. Nasrallah/Hizb'Allah has proven this. Even back in 2002 I was posting that a wall would not keep out missiles and artillery and mortar rounds. Hizb'Allah has neutralized walls, damaged Israel's economy with the primitive Katushya rockets it deploys.
I will admit I got lulled to sleep for a while by the effectiveness of the West Bank fence/wall in stopping suicide bombers. When (if) Olmert gives away broad parts of the West Bank is when Iran will bring in Katushyas and anti tank missiles
A border is a perfect wall. Kill them inside the border. If they do not have a visa make them leave, I have to when my visa expires, why shouldn't an Arab have to.
Or are they too special...
