Boehner is making it clear that although the President is determined to sign an agreement with medieval, lunatic, apocalyptic mullahs that are fond of making apocalyptic threats, that would result in them obtaining nuclear arms, the Congress recently elected by the American people is opposed to such an agreement and understands what is at stake.
Without the formal agreement of 2/3 of the Senate, any agreement with Iran is limited to Obama's term in office...IF Congress allows him the monies to abide.
In other words, it's not worth the shot and powder to blow it hell.
