However Israel's actions were not just for economic reasons, they had political purposes. For Eshkol, control of the water ways was vital for Israeli survival, otherwise ˜the Zionist dream could not be realized'.7 However, this "dream " threatened Syria and Jordan as it would significantly reduce water available to their countries. After the Suez Crisis, Arab discontent over the water issue, began to heighten and the Arab countries started to plan a diversion project of their own which would divert the water from the rivers that Israel used, severely reducing their access to fresh water.8.
Syria emerged as the main actor in seeking to sabotage Israel's water system, which began a long chain of Israeli-Syrian clashes in the DMZ that became significantly violent. The Israelis started to provoke the Syrians by sending tractors to plough the fields in the DMZ, wait for them to be fired on and then retaliate. At first these tractor-induced cross-fires ˜were short with little damage to either side',9 however Israel had pushed their luck when on April 7th 1967 two tractors entered the DMZ near Kibbutz Ha'on. The Syrians opened fire, however this time with much more force; shelling Israeli settlements in the area. It quickly escalated in a full-scale attack, resulting in aerial engagements between the two sides. The IAF managed to shoot down all six of the Syrian MiGs, and Shlaim argues that this ˜started the countdown of the Six Day War'.10 Shlaim is not wrong, as this "miniwar " was the first time the IAF infiltrated all the way to the Syrian capital; this was a direct threat to Syria, and they sought revenge. It is questionable whether Israel retaliated in such an extravagant way because they wanted war with Syria. As has been argued, Syria was the main source of the problem " launching attacks themselves and using Fatah also as a weapon against the Israelis.
