 Members of the Israel on Campus Coalition include the Zionist Organization of America, AIPAC, Americans for Peace Now, the Anti-Defamation League, Kesher, the Union of Progressive Zionists (Ameinu and Meretz USA/Partners for Progressive Israel).Although these groups are largely united in their support of Israel, there was a major internal conflict in 2007 when the right-wing Zionist Organization of America unsuccessfully attempted to remove the left-wing Union of Progressive Zionists from the coalition after the latter group sponsored lectures by a group of former Israel Defense Forces soldiers who criticized the Israeli Occupation of the West Bank and Gaza.There are some who feel that pro-Israel activism on college campuses can cross the line from advocacy to outright intimidation.
