Rubenberg 1989, p. 358: “The labeling of individuals who disagree with the lobby’s positions as “anti-Semitic” is a common practice among Israel’s advocates. For example, when Senator Charles Mathias [R., Maryland] voted in favor of the AWACs sale to Saudi Arabia, a Jewish newspaper in New York commented: “Mr. Mathias values the importance of oil over the well-being of Jews and the State of Israel. The Jewish people cannot be fooled by such a person, no matter what he said, because his act proved who he was.” Former Congressman Paul “Pete” McCloskey [R., California] also has had the charge of anti-Semitism leveled at him: “When I ran for reelection in 1980, I was asked a question about peace in the Middle East, and I said if we were going to have peace in the Middle East we members of Congress were going to have to stand up to our Jewish constituents and respectfully disagree with them on Israel. Well, the next day the Anti-Defamation League of the B’nai B’rith accused me of fomenting anti-Semitism, saying that my remarks were patently anti-Semitic.” Indeed, it may be that the weapon of greatest power possessed by the pro-Israeli lobby is its accusation of anti-Semitism. George Ball comments: “They’ve got one great thing going for them. Most people are terribly concerned not to be accused of being anti-Semitic, and the lobby so often equates criticism of Israel with anti-Semitism. They keep pounding away at that theme, and people are deterred from speaking out.” In Ball’s view, many Americans feel a “sense of guilt” over the Holocaust, and the result of their guilt is that the fear of being called anti-Semitic is “much more effective in silencing candidates and public officials than threats about campaign money or votes.””
Do you have a source for Israel admitting it? That Wikipedia article is long!
