For example the Apartheid Wall in Israel - a "liberated" country.
"..T he Israeli West-Bank barrier is a barrier being constructed by the State of Israel, consisting of a network of fences with vehicle-barrier trenches surrounded by an on average 60 meter wide exclusion area (90%) and high concrete walls up to 8 meters high (10%).[1] It is located mainly on Israeli-occupied territories in the West Bank and partly along the 1949 Armistice line, or "Green Line" between Israel and Jordan which now demarcates the West Bank. As of April 2006[update], the length of the barrier as approved by the Israeli government is 703 kilometers (436 miles) long. Approximately 58.04% has been constructed, 8.96% is under construction, and construction has not yet begun on 33% of the barrier.[2] The Jerusalem Post reported in July 2007 that the barrier may not be completed until 2010, seven years after it was originally supposed to be finished.[3]
The barrier is highly controversial. Supporters argue that the barrier is necessary to protect Israeli civilians from Palestinian terrorism, including the suicide bombing attacks that increased significantly during the Al-Aqsa Intifada;[4] The significantly reduced number of incidents of suicide bombings from 2002 to 2005 has been partly attributed to the barrier;[5]
Opponents of the barrier object that the route substantially deviates from the Green Line into the occupied territories captured by Israel in the Six-Day War of 1967. Therefore they argue that the barrier is an illegal attempt to annex Palestinian land under the guise of security,[6] violates international law,[7] has the intent or effect to pre-empt final status negotiations,[8] and severely restricts Palestinians who live nearby, particularly their ability to travel freely within the West Bank and to access work in Israel.[8] In a 2004 finding, the International Court of Justice declared that "Israel cannot rely on a right of self‑defence or on a state of necessity in order to preclude the wrongfulness of the construction of the wall. Construction of the barrier is "contrary to international law."[9]
Settler opponents, by contrast, condemn the barrier for appearing to renounce the Jewish claim to the whole of the Land of Israel.[10]
