Many treat the second Lebanon war as though it were a direct continuation of the 1973 October War. That includes the voices decrying the government and blaming the generals, and those defending the generals against the politicians, all the way to the reservists’ protest movement.
But the main conclusions of the October War were not drawn after the Agranat Commission, but rather through negotiations with Egypt and the willingness to return territories conquered in 1967. That was the primary conclusion from the war — and not changing the behavioral pattern of Military Intelligence, which then began to warn about the danger of war at every Knesset Foreign Affairs and Defense Committee meeting, lest it be deemed complacent by some future review board.
There were elections in 1974, and an alignment government was voted in, and only in 1977 did a political upheaval occur; by means of elections, not an investigative committee. From there it was a short way to Camp David with Egypt.
