M. J. Rosenberg, is (2006) director of Policy Analysis for Israel Policy Forum. A long time Capitol Hill staffer, he is also a former editor of AIPAC's Near East Report. In early 2012, he left Media Matters because it was being attacked for his criticisms of Israel. He started a new blog called MJayRosenberg.com.
Rosenberg worked for AIPAC in the 1980's but after the Oslo agreement of 1993 broke with the AIPAC approach and became an active supporter of the two-state solution. Previously he spent 17 years on Capitol Hill and five as as political appointee at the Clinton State Department. Rosenberg first came to the attention of the Jewish community when he authored "To Uncle Tom & Other Such Jews" in the Village Voice 1969. A college junior, Rosenberg urged leftwing students not to "support every national lineration struggle but your own: Zionism." That article helped kick off the radical Zionist movement on US campuses. Rosenberg moved away from that position after Oslo.
From Rosenberg's IPF profile:
M.J. Rosenberg is the Director of Policy Analysis for Israel Policy Forum (IPF), a position he has held since the spring of 1998. In this position, MJ heads IPF's Washington, D.C. office and writes IPF Friday, a weekly opinion column on the Arab-Israeli conflict which is widely circulated throughout the United States and the Middle East. In addition, MJ has published numerous op-eds, in the national and Jewish press.
MJ spent eighteen years within the United States government, fourteen on Capitol Hill as an aide to Representatives Jonathan Bingham (D-New York), Edward Feighan (D-Ohio) and Nita Lowey (D-New York) and Senator Carl Levin (D-Michigan). Immediately prior to coming to IPF, he was a political appointee to USAID, where he served as Chief of Staff for Thomas A. Dine, the head of the Eastern Europe/NIS Bureau of USAID.
From 1982 to 1986, MJ was editor of Near East Report, the American Israel Public Affair Committee's (AIPAC's) biweekly publication on Middle East Policy.
Rosenberg may seem to have come a long way since his AIPAC days. But he is still a Zionist and he still uses the Zionist tactic of smearing anti-Zionists as anti-Semites - on October 2013, he falsely accused Ali Abunimah of anti-Semitism.
