LOTR, a Zionist is someone who subscribes to Jewish Nationalism. He supports the State of Israel while disagreeing, sometimes strongly, with some government policies. He should also at least want to make aliya as soon as possible. He does not fight with Chareidim. Some of them fight but they are just proving how much they should enlist in the IDF.
Laskern, he was a descendant of the Tzanzer Rebbe. Rabbi Abahu says (Chulin 63b) that the ראה (a type of hawk) is called that because he sits in Bavel and sees a נבלה in EY. The Tzanzer says that there is nothing more unclean than that.
