Since July the Israel Lobby and other opponents of the understanding reached by the White House and other parties to limit the Iranian nuclear program have been warning that any celebration would be premature, as the agreement is far from a done deal. President Obama survived initial attempts to create legislative hurdles hindering implementation of the pact, but there are clear signals that the battle is far from over.

Congress is again cranking up its efforts to overturn the agreement, incorporating conditions into sometimes unrelated legislation that seek to circumvent or limit the authority of the president to conduct the nation's foreign policy. This is being referred to as "round two" by critics of the White House, and Mark Dubowitz, executive director of the neoconservative Foundation for the Defense of Democracies, is warning that "there will be many, many more rounds" if needed.
