I’ve never deluded myself in thinking that Isaac Herzog is a great ideologue, willing to sacrifice himself for his principles. I remember him talking with disdain about Shimon Peres’s “crawling” to the Sharon government as it carried out the Gaza disengagement, before joining the same government a short while later. I remember him giving dazzling speeches denouncing Ehud Barak’s leadership, only to subsequently support him in the 2007 race for the Labor Party leadership.
