J Street differed significantly with Obama over whether Israel had the right to use military force in self-defense against Hamas rocket attacks on Sderot. J Street condemned Operation Cast Lead within 24 hours after it started. Furthermore, J Street rewarded Representative Donna Edwards with campaign donations for voting "present" rather than "yes" on Speaker Pelosi's January 9 resolution endorsing Israel's right to self-defense. In contrast, Obama resisted calls to condemn Operation Cast Lead, giving tacit support to the Israeli military operation. Obama, unlike J Street, took the position of Israel's center-left Labor Party or its leftwing Meretz Party that the initial stages of Operation Cast Lead were justified. It is false to claim that J Street's positions are "in line" with those of Obama.
