The legend arose after Churchill himself boasted in his later years that he had created Jordan with the stroke of a pen, one Sunday afternoon in Cairo. Nevertheless, the involvement of alcohol in the drawing of the border as well as Churchills claimed sole responsibility over it are almost certainly apocryphal. The acute angle created points directly towards the Dead Sea on the side of Jordan. The triangular part of Saudi Arabia bordering Winstons Hiccup and thus jutting into Jordan is also the closest part of the country to Jerusalem, at just over 100 miles. Complex and seemingly arbitrary Middle Eastern borders such as Winstons Hiccup often took the movements, conversely, the border between Jordan and Israel is governed more heavily. Officially, the borders were set by a series of agreements between the United Kingdom and the government of what eventually became Saudi Arabia, first formally defined in the Hadda Agreement of 1925. In 1965, Jordan and Saudi Arabia concluded an agreement that realigned and defined the boundary. The realignment resulted in exchange of territory, and Jordans coastline on the Gulf of Aqaba was lengthened by about 18 kilometers.
