The history of the use of barriers for the security, defense and sovereignty of countries is closely related to the legality of the use of the West Bank Barrier, an architectural work wielded by the State of Israel as a political-military strategy against the legal mandate of IHL for Palestine. With a methodological approach based on documentary research through content analysis of newspapers, magazines, books, films, photographs, official documents and websites that relate the Israeli-Palestinian conflict with the Barrier, key concepts such as border, human rights, international humanitarian law, public international law, political realism theory, security and self-defense are analyzed in order to elucidate the current situation of an occupied state and territory. This will allow historians and international analysts to understand that the West Bank Barrier is the best way for the international community to do nothing, and in turn to question the role of Israel in order to justify its survival in the Middle East and drastically change the landscape of the conflict and the international legal framework.
