The Iranian nuclear agreement announced on July 14 is unconstitutional, violates international law and features commitments that President Obama could not lawfully make. However, because of the way the deal was pushed through, the states may be able to derail it by enacting their own Iran sanctions legislation.

President Obama executed the nuclear deal as an executive agreement, not as a treaty. While presidents have used executive agreements to arrange less-important or temporary matters, significant international obligations have always been established through treaties, which require Senate consent by a two-thirds majority.

The Constitution’s division of the treaty-making power between the president and Senate ensured that all major U.S. international undertakings enjoyed broad domestic support. It also enabled the states to make their voices heard through senators when considering treaties—which are constitutionally the “supreme law of the land” and pre-empt state laws.

The Obama administration had help in its end-run around the Constitution. Instead of insisting on compliance with the Senate’s treaty-making prerogatives, Congress enacted the Iran Nuclear Agreement Act of 2015. Known as Corker-Cardin, it surrenders on the constitutional requirement that the president obtain a Senate supermajority to go forward with a major international agreement. Instead, the act effectively requires a veto-proof majority in both houses of Congress to block elements of the Iran deal related to U.S. sanctions relief. The act doesn’t require congressional approval for the agreement as a whole.

The best approach to Iran in the wake of President Obama’s deal is to recognize the complex nature of the problem, and the absolute need for a well-considered and comprehensive approach. The agreement cannot and should not be simply repudiated on the next president’s first day in office, as some Republican presidential contenders have suggested. The agreement is terrible, but once concluded, the national interest requires that it be undone only with care, patience, and masterful diplomacy—an approach championed by Gov. Jeb Bush and Senator Lindsey Graham. Indeed, to suggest otherwise, is to fail to appreciate the full extent of the damage done by the deal and the difficult foreign-policy legacy President Obama is leaving for his successor.

First and foremost, simply abrogating the deal—which already has been enshrined in a Chapter VII UN Security Council Resolution binding on the United States and all members of the United Nations—would actually put the United States in violation of its international obligations and will hand tremendous strategic benefits to Tehran. This may be inevitable, since Russia and China will certainly take advantage of any American action against Iran to score diplomatic and strategic points against us. But, we do not have to make it easy for them, and we should not.

In addition, whatever action the new president takes on January 20, 2017, Iran will remain free of the vast majority of the sanctions that brought it to the bargaining table in the first place. While the next president will be able to vitiate promptly President Obama’s waivers of the existing statutory sanctions—some of which are certain to go beyond his lawful waiver authority—thereby making the existing domestic statutory sanctions available, it would still make sense to consult with Congress on whether the sanctions regime needs adjustment in light of new circumstances.

Although President Obama has ignored Congress, or affirmatively sought to curtail its constitutional prerogatives, the next President should work with Congress and must seek to build a bipartisan consensus on how to meet the Iranian challenge. As Supreme Court Justice Robert Jackson wrote in the landmark case of Youngstown Sheet & Tube Co. v. Sawyer (1952), a president acts at the height of his constitutional authority when working with, rather than against, Congress.

Nuclear talks between Iran and the U.S. recommenced Jan. 14, ahead of full international talks with senior officials from the U.S., U.K., France, Russia, China and Germany two days later. A final agreement is to be reached no later than June 30. Nothing less than Middle Eastern and global security hangs in the balance.

That security depends on verifiable elimination of Iran’s nuclear-weapons and ballistic-missile programs. Unfortunately, the Obama administration is likely to accept a deal leaving in place a substantial Iranian nuclear-weapons infrastructure, including uranium-enrichment capability, long-range ballistic missiles and the ability to deploy a rudimentary nuclear force on short notice. A course correction that only Congress can effect is urgently needed.

It is difficult for Congress to stop a president determined to sign an agreement with foreign leaders. And as this newspaper pointed out in a recent editorial, President Obama has threatened to veto any legislation to impose further sanctions on Iran if the June 30 deadline is not met. Still, Tehran’s insistence that existing U.S. sanctions be lifted as part of a nuclear-weapons agreement gives U.S. lawmakers substantial leverage. The collapse of oil prices, which dealt a heavy blow to the already weakened Iranian economy, has further increased this leverage. Here is what Congress should do:

First, Congress should insist that any Iranian agreement take the form of a treaty. The Constitution requires that treaties be made only with the advice and consent of the Senate. At the time it was adopted, and throughout most of U.S. history, agreements fundamentally ordering the relationship between the U.S. and foreign nations took the form of treaties, not executive orders. A mere executive agreement, which Mr. Obama may use to evade congressional constraints here, would be constitutionally insufficient. Read more »

Hamas claims that former president Jimmy Carter’s recent meeting with its leader, Khaled Meshal, marks its recognition as a “national liberation movement” — even though Hamas rockets fired from the Gaza Strip, which Hamas rules as an elected “government,” continue to rain down on Israel’s civilian population. While Hamas is clearly trying to bolster its legitimacy, the conflict along Israel’s southern border has a broader legal dimension — the question of whether, as a matter of international law, Israel “occupies” Gaza. The answer is pivotal: It governs the legal rights of Israel and Gaza’s population and may well set a legal precedent for wars between sovereign states and non-state entities, including terrorist groups such as al-Qaeda.

Israel’s critics argue that Gaza remains “occupied” territory, even though Israeli forces were unilaterally withdrawn from the area in August 2005. (Hamas won a majority in the Gazan assembly in 2006 and seized control militarily in 2007.) If this is so, Jerusalem is responsible for the health and welfare of Gazans and is arguably limited in any type of military force it uses in response to continuing Hamas attacks. Moreover, even Israel’s nonmilitary responses to Hamas-led terrorist activities — severely limiting the flow of food, fuel and other commodities into Gaza — would violate its obligations as an occupying power.

The critics should look no further than the U.S. to see what consequences can ensue.

By DAVID B. RIVKIN JR. And KARL R. MOOR

While the Israeli political scene is no stranger to strident criticisms directed at senior government officials and their policies, the recent attacks on Prime Minister Benjamin Netanyahu and Defense Minister Ehud Barak over their policies toward Iran are a dangerous luxury.

Numerous retired security officials who do not lack a private voice or influence within a small nation. including former Shin Bet head, Yuval Diskin, ex- Mossad chief, Meir Dagan, and Former IDF Chief of General Staff Gabi Ashkenazi, have launched broadsides against the current Israeli government’s dire assessments of the Iranian threat and the best ways of dealing with it.
