The Patron and The Client: How American Weapons Money Explains Israel Defiance

"Trump's agreement does not bind us. Israel is not subject to the United States."
— Itamar Ben-Gvir, National Security Minister of Israel, June 15, 2026

The memorandum of understanding signed this week in Switzerland was supposed to end four months of war. Whether it does may depend less on Washington and Tehran than on a government in Jerusalem that helped start the conflict, now refuses to stop its piece of it, and is funded almost entirely by the country whose diplomatic achievement it is undermining.

Prime Minister Benjamin Netanyahu told reporters Israel will remain in its self-declared security zone in southern Lebanon "for as long as necessary." National Security Minister Itamar Ben-Gvir was more direct, writing on social media that "Trump's agreement does not bind us" and that "Israel is not subject to the United States."

Iran has said with equal clarity that continued Israeli military operations in Lebanon constitute a violation of the memorandum, and that any Israeli occupation of Lebanese territory is incompatible with the deal it signed. The agreement, brokered by Pakistan and Qatar and signed in Bürgenstock, is supposed to open sixty days of negotiations over Iran's nuclear program and the lifting of sanctions. That second phase cannot begin if the first phase — a halt to hostilities — is contested at its most basic definition.

The problem is structural, and it predates this agreement by decades.

Israel currently occupies approximately 570 square kilometers of southern Lebanese territory, a figure that has expanded beyond the buffer zone it declared in April following a ground invasion that began in early March. Israeli forces have pushed past the Litani River toward the Zahrani River, issued evacuation orders covering roughly one-fifth of Lebanon's territory, and as of Thursday published a new military map showing an expanded zone of control. More than 3,700 people have been killed in Lebanon since the campaign began on March 2. Over a million have been displaced from their homes.

Israel is conducting this campaign with American weapons purchased with American taxpayer dollars. That relationship — durable, bipartisan, and structurally embedded in both countries' defense economies — is the context without which Israeli defiance cannot be fully understood.

Under a ten-year Memorandum of Understanding signed in 2016 and running through 2028, the United States provides Israel $3.8 billion annually in security assistance: $3.3 billion through the Foreign Military Financing program and $500 million for cooperative missile defense. The money does not change hands in any ordinary sense. It transfers from State Department accounts directly to American defense contractors. Israel selects from approved American weapons systems; the Pentagon executes the contracts; Lockheed Martin, Boeing, and RTX collect. By 2028, one hundred percent of the FMF allocation must be spent on American-made goods and services. The money, by design, never leaves the American economy.

Since October 7, 2023, Congress has authorized more than $16 billion in additional military aid on top of the baseline. As of April 2026, active Foreign Military Sales cases with Israel were valued at $39.2 billion. Since 1948, cumulative American aid to Israel exceeds $174 billion — more than to any other country in the postwar era.

For the United States, the structure keeps the spending circulating domestically — through factories in Fort Worth, Hartford, and St. Louis, and supply chains across forty-five states — which explains the robust congressional support that has survived administrations of both parties and every shift in public opinion about the Middle East. The relationship is not a cash transfer. It is an industrial partnership in which Israel provides the battlefield and the United States provides the weapons, with contractors on the American side collecting whether the diplomacy succeeds or fails.

This is the architecture that makes Israeli defiance possible, and that constrains Washington's ability to respond to it.

Trump has made no secret of his frustration with Netanyahu. He called him "a very difficult guy," said Israel should be "very thankful" for the American-brokered agreement, and warned Israel not to "blow it" as the deal was being finalized. These are not the words of a patron with easy leverage over a client; they are the words of a president who has discovered that the relationship runs in more directions than one.

Because the weapons pipeline is embedded in American law, in congressional appropriations, and in multi-year contracts, it does not respond quickly to diplomatic temperature. A president cannot easily threaten to cut off arms to a country whose procurement is authorized by statute, whose contracts were signed years in advance, and whose supplier base employs workers in nearly every congressional district. The political cost of using the aid relationship as genuine leverage — as opposed to rhetorical frustration — is significant enough that it has never been seriously attempted by any administration despite periodic declarations that it might be.

Netanyahu understands this. So does his far-right coalition, whose members have been explicit this week that they consider the American agreement non-binding and intend to continue military operations in Lebanon regardless of what it says. Iran also understands it, which is why Iranian officials have repeatedly tied the viability of negotiations to Israeli behavior in Lebanon while framing American expressions of frustration as insufficient without accompanying action.

The agreement will hold or fail in the gap between what Washington is willing to demand of Jerusalem and what Jerusalem is willing to concede to Washington. That gap is narrower than it appears from the outside, and it is underwritten by a $38 billion memorandum of understanding, a supply chain across forty-five states, and seven decades of institutional investment that neither government has any short-term interest in renegotiating.

The Islamabad Memorandum was signed remotely on June 17, with President Trump signing at the Palace of Versailles and Iran's President Pezeshkian signing in Tehran. Implementation talks opened Thursday at Bürgenstock, Switzerland. Sixty days of negotiations over Iran's nuclear program and sanctions relief are scheduled to follow. Israeli troops remain in southern Lebanon.
