Mr Rosenblum You have hit the nail on the head, and by the way a very similar phenomenon is taking place in the Diaspora, especially the UK where I am Chair of Meretz UK. If you look at the JC Blog you will see what some of these "Nationalists" are writing, and alarmingly they seem to have a large number of acolytes. All of them believe Yisrael Beiteinu has all the answers, whereas the lefties are self-hating Jews, they wish to appease the enemy, and they must be silenced by bully boy tactics. So by extension this latest form of "Zionism" has spread like a malignancy to the Jewish world outside of Israel.
