<P> During the Cold War, one example of "no man's land" was the territory close to the Iron Curtain . Officially the territory belonged to the Eastern Bloc countries, but over the entire Iron Curtain there were several wide tracts of uninhabited land, several hundred meters in width, containing watch towers, minefields, unexploded bombs and other such debris . </P> <P> The U.S. Naval Base at Guantánamo Bay, Cuba is separated from Cuba proper by an area called the Cactus Curtain . In late 1961, Cuba had its troops plant an 8 - mile (13 km) barrier of Opuntia cactus along the northeastern section of the 28 - kilometre (17 mi) fence surrounding the base to prevent economic migrants fleeing from Cuba from resettling in the United States . This was dubbed the "Cactus Curtain", an allusion to Europe's Iron Curtain and the Bamboo Curtain in East Asia . U.S. and Cuban troops placed some 55,000 land mines across the no man's land, creating the second - largest minefield in the world, and the largest in the Americas . On 16 May 1996, Bill Clinton, the President of the United States, ordered their removal . The U.S. land mines have since been replaced with motion and sound sensors to detect intruders . The Cuban government has not removed the corresponding minefield on its side of the border . </P> <P> The 1949 Armistice Agreements between Israel and Jordan were signed in Rhodes with the help of UN mediation on 3 April 1949 . Armistice lines were determined in November 1948 . Between the lines territory was left that was defined as no man's land . Such areas existed in Jerusalem, in the area between the western and southern parts of the Walls of Jerusalem and Musrara . A strip of land north and south of Latrun was also known as "no man's land" because it was not controlled by either Israel or Jordan in 1948--1967 . </P> <P> In 1885, the United States Interior Department ruled that what was called "The Neutral Strip" was public land and that squatter homesteads were invalid . The Strip began to be called No Man's Land around 1886 after one official stated "no man can own the land". </P>
