In 1991, the General Assembly adopted Resolution 4686, which effectively negated Resolution 3379. Use of its veto power to prevent the Security Council from issuing resolutions condemning Israeli military action has frequently divided the U.S. from the Soviet Union, China and France in the Security Council; since 1989, the U.S. government has dissented against Security Council resolutions on 12 occasions out of 17 total instances when a permanent member vetoed. Of these 12 occasions, only two related to issues other than the Israeli–Palestinian conflict.[citation needed] In 2009, the U.S. government abstained from Security Council Resolution 1860, which called for a halt to Israel's military response to Hamas rocket attacks, and the opening of the border crossings into the Gaza Strip.
