Here is an article that says the whole IDF and Israeli government has become Le Carre like in their aversion to battle. There is certainly a strong element of that in Israeli society as well.
The much maligned settlers still have the guts and the will. That's why the left hates them so much.

Does that include the left in Israel? The fact that Sharon is so well supported, despite forced evictions, is a testimony to me that current Israeli thinking is similar to the pacifistic denial that got Polish Jews killed in the Warsaw Ghetto.
