The June War changed the regional balance in the Middle East, weakening the position of Arab states. The three Arab countries directly involved in the war with Israel lost an important and strategic part of their territories. After a swift air and ground attack, Egypt lost the Sinai Peninsula, which resulted in the closure of the Suez Canal, unfavourably affecting the Egyptian state budget. Syria was pushed out of the Golan Heights – an excellent vantage point for shelling Damascus. This military weakness led top governmental representatives to consider the possibility of a new Israeli attack. Jordan suffered a real loss, not only of territorial but also religious significance. It lost control of the whole West Bank of the Jordan River, including East Jerusalem. Jordanian King Eusayn was aware of the fact that the Israeli seizure of the West Bank called for quick action as a long-term occupation could thwart the unification of the kingdom.
