As an American centrist who in Israel would be considered a leftist (which shows how far to the Right Israel's democracy is), I will now rank Israel's prime ministers. I rank them primarily on their contributions to Israeli security and to peace with Israel's neighbors, but also on their contributions to Israeli democracy. I will not rank those prime ministers whose term in office was less than two years, as less than half a term is too little to fairly judge a prime minister by.
First, David Ben-Gurion (1948-1954, 1955-63) Ben-Gurion had the historic understanding of his environment, of what history demanded and of timing to build the framework for a state during the 1930s and 1940s as head of the Jewish Agency. He then managed to divorce the Jewish Yishuv from Britain in 1945, without provoking a fatal reaction. He conducted a victorious war strategy in 1948-49 after having wisely accepted the UN partition plan. Later he built an alliance with France to replace the British connection. I could write a column about all of his faults, but in the largest matters he was correct.
