Israel has similar barriers along its borders with Lebanon, Syria, and Jordan. In fact, a fence already surrounds the Gaza Strip and not a single suicide bomber has managed to get across the Gaza barrier into Israel. Ironically, after condemning Israel's barrier, the UN announced plans to build its own fence to improve security around its New York headquarters.
Although critics have sought to portray the security fence as a kind of "Berlin Wall," it is nothing of the sort. First, unlike the Berlin Wall, the fence does not separate one people, Germans from Germans, and deny freedom to those on one side. Israel's security fence separates two peoples, Israelis and Palestinians, and offers freedom and security for both. Second, while Israelis are fully prepared to live with Palestinians, and 20 percent of the Israeli population is already Arab, it is the Palestinians who say they do not want to live with any Jews and call for the West Bank to be judenrein. Third, the fence is not being constructed to prevent the citizens of one state from escaping; it is designed solely to keep terrorists out of Israel. Finally, only a tiny fraction of the barrier (less than 3% or about 15 miles) is actually a 30 foot high concrete wall, and that is being built in three areas where it will prevent Palestinian snipers from around the terrorist hotbeds of Kalkilya and Tul Karm from shooting at cars as they have done for the last three years along the Trans-Israel Highway, one of the country's main roads. The wall also takes up less space than the other barriers, only about seven feet, so it did not have a great impact on the area where it was built.
