why do you think they are building that wall?
i don't completly agree with it either since no wall should seperate man, but they were (and maybe still) left with no other choice. I say were because the Arafat era was a terrorist in office who encouraged terrorism for others.
I'd only hope that Abbas will do much much better in perceiving peace, and that will time only tell. Now that the wall is allready set, they might as well leave it their as a precaution.
The rate of terrorist attacks in Israel has drastically lowered since the wall was build, it has saved over hundreds of lifes allready... Now if i were a president and i'd had to choose between a pile of bricks and a thousand of my citizens in the long term, i'd would choose a pile of bricks.
If Palestine ever renounces it's terrorists nature i'd be glad to see the day that the wall would be broken down... i'd be glad if he'd be broken down in Cyprus as well, seems like Israel isn't the only country wich thinks that muslims can be a serious threat to life.
