GOP senators publicly avowed that Israeli diplomats lobbied them to oppose U.S. policy toward Iran

"The Senate Banking committee is considering some of the harshest sanctions yet against Iran.  This legislation is opposed by the Obama administration since it’s on the verge of securing a nuclear agreement with Iran.  One aspect that would be necessary to implement the agreement would be softening some parts of the anti-Iran sanctions regime.  That’s why the Israeli government, which has all but called the agreement a ticket to World War III, wants even worse sanctions than currently exist.  This would tie Obama’s hands and prevent him from implementing any agreement with Iran.  That would be honky-dory for the Israelis who want no agreement and an eventual war against the Iranian regime."
