J Street was formed a year and half ago as a more liberal alternative to the nation's main pro-Israel lobbying organization, the American Israel Public Affairs Committee, better known as AIPAC. J Street's executive director has said that he wants his group to be the "blocking back" for Mr. Obama's efforts to bring peace to the Middle East.
But by taking on the long-established AIPAC and the hawkish Israeli government, and by embracing individuals who have expressed hostility to Israel, J Street also has alienated some veteran Israel supporters in Washington. For example, one of next week's speakers is a Muslim activist who has said that Israel should be considered a suspect in the Sept. 11, 2001, terrorist attacks.
