In mid-May 1967, massive Egyptian forces began entering the Sinai Peninsula, a blatant violation of the understandings reached under the auspices of the US administration after Operation Kadesh. The core of the understandings was that Sinai was to remain a demilitarized zone, in which UN forces would be stationed in order to separate between Israel and Egypt. President Gamal Abdel Nasser went even further than deploying his army in Sinai and at the same time ordered the UN forces to leave Sinai and Gaza. He claimed that Egypt was free to do as it pleased in these territories since they were under Egyptian sovereignty. UN Secretary U Thant acceded to his demand. Egypt continued to escalate the tension with Israel when it announced the blocking of the Straits of Tiran to Israeli shipping, with the clear knowledge that Israel would view this as a casus belli and with the understanding that the blocking of the straits would put Israel in an untenable economic and strategic situation, since the vast majority of its oil supply arrived from Iran by way of the Straits of Tiran.
