Plan Dalet (Hebrew: תוכנית ד', Tokhnit dalet "Plan D") was a Zionist military plan executed in the civil war phase of the 1948 Palestine war for the conquest of territory in Mandatory Palestine in preparation for the establishment of a Jewish state.[1] The plan was requested by the Jewish Agency leader and later first prime minister of Israel David Ben-Gurion, and developed by the Haganah and finalized on March 10, 1948. Historians describe Plan Dalet, in which Zionist forces shifted to an offensive strategy, as the beginning of a new phase in the 1948 Palestine war.[2][3]
The plan was a set of guidelines to take control of Mandatory Palestine, declare a Jewish state, and defend its borders and people, including the Jewish population outside of the borders, "before, and in anticipation of" the invasion by regular Arab armies.[4][5][qt 1][6][7][8] Plan Dalet specifically included gaining control of areas wherever Yishuv populations existed, including those outside the borders of the Jewish state.[9]
This strategy is subject to controversy, with some historians characterizing it as defensive, while others assert that it was an integral part of a planned strategy for the expulsion, sometimes called an ethnic cleansing, of the area's native inhabitants.[10]
