When on the march, they do not stop at the edge of the sea but march straight on into the water and drown. Lately, many members of the Knesset behave similarly. The president decides and executes. The ministers are his personal assistants. His decisions are approved by popular referendum.

In France this happened because everybody was fed up with a parliament that was obviously incapable of satisfying the general demand for an end to the war in Algeria. Power was transferred to a general who despised politicians. He instituted a system of government by plebiscite. Parliament became unimportant. Ehud Barak has not yet proven that he has the stature of a de Gaulle.
