The Rafah Agreement was a fraud on both Israelis and Palestinians. And Egypt was not a party to it. And the Agreement expired before June 2006 and was never renewed. Egypt doesn't get along with Hamas and with US encouragement, Egypt participates in the Siege of Gaza. They also allow Israel to maintain the fiction that Israel is not responsible for Gaza. Israel maintains that the Palestinians are occupied, but only in the West Bank. Somehow, Israel cannot conceive that there might be a connection between Gaza and the West Bank Palestinians, legally. But it is tied up in the Oslo Accords that Israel would like to abolish, except for the legal fictions it enables. Egypt could open Rafah any time it wants and violate NO International Agreement to which Egypt is a party. They only need encouragement. Sorry to be so disagreeable.
