The Symington and Glenn Amendments

The Symington Amendment does not ask the President to consider cutting off aid. It says assistance “shall be terminated.”

The statute, codified at 22 U.S.C. § 2799aa-1, applies to any country that delivers or receives uranium enrichment or reprocessing technology outside full-scope international safeguards. Its companion, the Glenn Amendment, covers detonating a nuclear device. Neither names a country. Neither contains an exemption for anybody.

Both have been enforced. Neither has ever been enforced against Israel, and the reason is not a waiver.

What the law does

Congress passed these amendments in the mid-1970s to give American nonproliferation policy financial teeth, and folded them into the Nuclear Non-Proliferation Act that Jimmy Carter signed in March 1978.

They are not self-executing. The trigger is a presidential determination that a country has done the prohibited thing. Once that finding is made, the cutoff follows.

Congress also built an escape hatch, and its design matters more than anything else in this case. A president may waive the cutoff, but only by certifying two things to Congress: that termination would seriously harm vital American interests, and that he has received reliable assurances the country will not acquire or develop nuclear weapons or help anyone else do so.

Read that second condition again with a country that already has the weapons in mind. It cannot be truthfully certified. The waiver was written for a state that might build a bomb, not one that already has.

It works on other countries

These are not dead letters.

Pakistan. The Symington Amendment was triggered in 1979 over imports of equipment for the unsafeguarded enrichment facility at Kahuta, and aid was cut. It was restored by waiver for strategic reasons after the Soviet invasion of Afghanistan, then cut again in October 1990, when President George H. W. Bush could no longer certify that Pakistan did not possess a nuclear weapon.

India. When India tested in 1998, Glenn Amendment sanctions applied. They applied to Pakistan’s tests that year too.

In each case the executive made the finding, the statute fired, and money stopped moving. The machinery works exactly as designed when Washington is willing to turn the key.

The third path

Israel is the textbook case these laws describe: an undeclared arsenal, built entirely outside international safeguards, in a state that never joined the Non-Proliferation Treaty.

The statute has never been triggered in half a century, and not because any president used the waiver. Using the waiver would require first making the determination, and making the determination is the thing that has never happened.

So the executive branch has taken a route the statutes do not contemplate: not deciding. No finding, therefore no trigger, therefore no cutoff and no waiver certification either. The law is not overridden. It is simply never allowed to become applicable.

This is what the 1969 Nixon-Meir understanding, documented in the Dimona case, actually purchases. Nixon pressed Israel to make no visible introduction of nuclear weapons and to conduct no test. An arsenal that is never declared and never detonated never forces the American government to formally know anything, and a government that knows nothing formally never has to act.

The commitment to not knowing has been maintained actively, not passively. In 2012 a directive known as WNP-136, “Guidance on Release of Information relating to the Potential for an Israeli Nuclear Capability,” barred federal employees and contractors from confirming Israel’s nuclear arsenal. Officials of a government that possesses the information are instructed not to say it out loud.

The argument on each side

Defenders of the arrangement say it is strategy, not evasion. Nuclear opacity, on this view, gives Israel a credible deterrent while denying its neighbours a formal pretext to start their own programs. A presidential determination would not just cut off aid; it would collapse a regional equilibrium and could set off exactly the arms race the nonproliferation regime exists to prevent. There is a serious version of this argument and it deserves to be stated as one.

The objection is narrower and harder to answer. Congress considered the possibility that cutting aid might damage American interests, and it wrote a remedy: the waiver. What Congress did not authorize was the executive nullifying a statute by declining to notice the fact that activates it. The off-ramp exists. It has never been used, because using it would require saying the thing out loud.

There is also a question about whether the Glenn Amendment even permits an off-ramp. Critics argue that where a state has actually detonated a device or received one, the President may have no waiver authority at all, and that new legislation from Congress would be required to authorize any relief.

What it adds up to

The United States has sent Israel hundreds of billions of dollars across the entire period these statutes have been law, without ever making the finding that would require either stopping the money or formally justifying its continuation.

The comparison is what gives the case its force. This is not a law nobody enforces. It was enforced against Pakistan, twice, and against India. Both are non-NPT nuclear states, the same category as Israel, and both had real aid cut for real reasons under these exact provisions.

The exemption has held across every administration of both parties for nearly fifty years, and it rests on a single proposition maintained at the highest levels of the American government: that the United States does not know Israel has nuclear weapons. Every relevant agency knows. A 2012 directive exists specifically to stop employees from confirming it. Congress wrote a law with a lawful way around it, and the executive branch chose instead to drive around the law itself.
