Netayahu is expected to criticize any deal-making with the Iranian regime.
Just four days before Prime Minister Benjamin Netanyahu’s speech to a joint meeting of Congress, the Obama administration sought on Friday to refute the Israeli leader’s expected critique, arguing that he has failed to present a feasible alternative to American proposals for constraining Iran’s nuclear program.
In a briefing for reporters, senior administration officials contended that even an imperfect agreement that kept Iran’s nuclear efforts frozen for an extended period was preferable to a breakdown in talks that could allow the leadership in Tehran unfettered ability to produce enriched uranium and plutonium.
The Obama White House might see a deal with Iran over "inspections" and their nuclear arms program as a major milestone - even a 'legacy' issue - so they want Congress to be in line. But Netanyahu obviously has a lot of concerns over dealing with the Iranian regime.
