Israeli Arms Sales to U.S. Adversaries

Summary

Over a period spanning roughly two decades, Israel transferred significant quantities of U.S.-origin and U.S.-funded military technology to China — a country the United States identified as a strategic competitor — and maintained an extensive arms and nuclear cooperation relationship with apartheid South Africa in violation of a UN Security Council arms embargo. In the early 1990s, then-CIA Director James Woolsey told a Senate Government Affairs Committee that Israel had been selling U.S. secrets to China for about a decade, and that the sales may amount to several billion dollars. The transfers produced repeated diplomatic crises between Washington and Jerusalem, U.S.-imposed sanctions, and documented instances of Israel lying to American officials about the nature of the transactions. No Israeli official faced legal consequences in the United States as a result.

Background

Israel’s defense industry occupies a structurally unusual position: it develops advanced weapons systems funded substantially by U.S. military aid and joint development programs, then exports those systems — and the technology embedded in them — on the open arms market. This arrangement creates a recurring tension: weapons developed with American taxpayer money and incorporating American technology are sold to countries whose military capabilities the United States actively seeks to limit.

Israel began selling military technology such as missiles, radars, and navigation systems to China in the 1980s, even before Beijing recognized Israel, and technology trade quietly intensified in the 1990s. During this same period, China was identified by the U.S. government as a primary strategic competitor in the Asia-Pacific and a potential adversary in any Taiwan Strait conflict.

What Happened

The China Transfers

CIA Senate Testimony (Early 1990s)

CIA Director James Woolsey, reading from a declassified CIA report before the Senate Governmental Affairs Committee, stated: “We believe the Chinese seek from Israel advanced military technologies that U.S. and Western firms are unwilling to provide.” Woolsey revealed that Israel had been selling military technology to China for over a decade, and that the sales may amount to several billion dollars.

Woolsey said the CIA was convinced China was also relying on its contacts in Israel to assist in developing advanced engines for the next generation of Chinese combat vehicles, and that China would rely on Israeli expertise to create sophisticated airborne radar employing technology that had been entrusted to Israel for the Arrow missile defense program — itself funded largely by the United States.

The Lavi/J-10 Transfer

The illegal transfer of plans for the Lavi aircraft from Tel Aviv to Beijing first became known to the Pentagon when an American surveillance satellite spotted several new fighter planes on the runway of a Chinese air base used for prototype testing. CIA imagery experts were stunned: China’s newest fighter jet was in fact a copy of the Israeli Lavi, which itself was modeled on the U.S. F-16 Fighting Falcon. The Lavi had been developed with approximately $1.5 billion in U.S. funding before Israel cancelled the program in 1987.

The Phalcon Affair (1999–2001)

During the 1990s, Israel was only second to Russia as a supplier of arms to China, and up to 20% of China’s arms were purchased from Israel.

Israel signed a contract worth approximately $1 billion to supply China with four Phalcon airborne early-warning radar systems — the Israeli equivalent of the U.S. AWACS platform — mounted on Russian-supplied aircraft. The United States went public with its long-held opposition when the first Russian-supplied plane destined for China arrived in Israel to be outfitted with the system. U.S. officials stated that the Phalcon radar system could impact the Taiwan Strait military balance in China’s favor.

Israeli Prime Minister Barak resisted U.S. calls to void the sale even in personal meetings with President Clinton and Defense Secretary William Cohen. Describing the final decision to cancel as “difficult,” Israel cited Cohen’s forceful April 2000 visit and rising opposition from U.S. Congress members — including long-time Israel supporters — as turning points.

The Harpy Drone Crisis (2003–2005)

China purchased an undisclosed number of Harpy loitering attack drones from Israel in 1994. In 2003, China contracted with Israel Aerospace Industries to upgrade the systems. Washington, concerned that the Chinese could use the Harpy in a future conflict over Taiwan that would endanger American forces, demanded that Israel not return the systems to China.

The U.S. believed that Israeli officials lied to them about the export. Officials claimed Israel was merely refurbishing old drones exported with American consent. The U.S. argued the drones had been upgraded using new technology that had been shared with Israel.

In response, the United States suspended cooperation with Israel on several long-range military development projects, including cooperation with the Israeli Air Force on the Joint Strike Fighter program. The Pentagon threatened to terminate Israeli participation in the F-35 program entirely. Israeli defense minister Shaul Mofaz canceled his trip to the United States following U.S. demands for a written apology. Senior Israeli defense ministry official Amos Yaron resigned over the controversy and was shunned by the Pentagon for months.

Ultimately, the Harpy drones were returned to China in 2005, without the requested upgrades.

The South Africa Relationship

While the China transfers sent U.S.-developed technology to a strategic competitor, the South Africa relationship was a different order: Israel armed an internationally embargoed regime and secretly cooperated with it on nuclear weapons.

From 1977 — the year of the UN arms embargo on South Africa — into the 1980s, South Africa was Israel’s biggest weapons customer. Weapons sales to South Africa grew from $70 million in 1973 to $1 billion in 1981.

Israel ignored the UN Security Council-imposed arms embargo on South Africa while telling the world that it was complying. A telegram from Israel’s deputy director of the Foreign Ministry explained the policy internally while maintaining the public denial.

The nuclear dimension of the relationship was documented through South African government archives declassified after the end of apartheid and analyzed by American academic Sasha Polakow-Suransky. Declassified documents reveal that Israeli Defense Minister Shimon Peres and South African Prime Minister P.W. Botha signed a broad-ranging agreement governing military ties that included a clause declaring “the very existence of this agreement” was to remain secret. Israel offered to sell South Africa nuclear warheads in 1975, in a deal that did not ultimately proceed.

In return for South Africa lifting safeguards on yellowcake uranium, Israel sent South Africa 30 grams of tritium — enough to build several atomic bombs, which South Africa did in the coming years.

A declassified 1977 State Department memorandum from Secretary of State Vance to President Carter noted: “Available information reveals nuclear cooperation between South Africa and Israel, possibly including plans to exchange nuclear-related materials,” and concluded: “If Israeli-South African cooperation involves nuclear weapons technology or materiel, it would hold gravest potential consequences for both governments.”

Official Response

The U.S. government’s responses across the three decades covered by this article followed a consistent pattern: private pressure, public restraint, eventual capitulation by Israel on the specific transaction in question, no lasting consequences, and continuation of U.S. military aid.

Consequences

No Israeli official was prosecuted or sanctioned personally for any of the transfers described in this article. U.S. military aid to Israel continued uninterrupted throughout the period. No further sales of military technology between China and Israel have been publicly reported since 2005. Chinese acquisition of Israeli defense technology through front companies and indirect channels has continued to be a documented U.S. concern, with the Biden administration warning Israel of Chinese “straw companies” operating inside the country as recently as 2022.

Significance

The pattern documented across thirty years of Israeli arms transfers to China and South Africa establishes something that individual incidents obscure: the relationship between the United States and Israel contains a documented and recurring structural conflict in which Israel transfers U.S.-funded and U.S.-origin military technology to countries the United States has identified as adversaries or sanctions targets, is caught, applies political pressure to soften the U.S. response, accepts a negotiated resolution that stops the specific transaction, and then continues the underlying practice. The CIA director testified to this dynamic before the Senate in the early 1990s. The U.S. government imposed its strongest documented sanctions against Israel — suspension of F-35 cooperation and demand for a written apology — not over espionage or political interference, but over drone upgrades to China. That those sanctions were lifted and full cooperation restored without any lasting policy change is consistent with every other incident documented in this archive.
