Newly surfaced US State Department cables from 1982 show Washington pressed Türkiye at a high level to halt a Turkish company’s export of electrical inverters to Pakistan’s nuclear program, part of a broader American effort that year to choke off suppliers to Islamabad’s weapons ambitions.
A May 1, 1982 State Department cable outlined talking points for a “high level demarche” instructing the US Embassy in Ankara to press the Turkish government to stop the export. The demarche was delivered on May 5, according to a follow-up cable from Ankara.
Turkish officials initially pushed back. A May 11 cable reported that Turkish authorities said the inverters “are not special nuclear equipment,” rejecting the premise that the sale required intervention.
Washington did not let the matter drop. A May 25 cable shows the US Secretary of State’s letter on the issue was personally delivered to a Turkish official. Weeks later, a June 14 cable recorded Turkish foreign ministry assurances that orders from the Turkish state electricity authority, EKA, would be complied with, suggesting Ankara ultimately moved to restrict the exports.
The Pakistan-related material sits within a much larger set of cables documenting US non-proliferation diplomacy across multiple countries in 1981-82, including parallel American efforts to block heavy water transfers to Argentina and Libya, reprocessing technology to Iraq, and separate procurement attempts by Pakistan for flash X-ray units and other dual-use equipment from Switzerland, West Germany, and other suppliers.
The cables do not describe the scope or scale of Turkish industrial involvement beyond the inverter shipments, nor do they characterize Türkiye as a primary or sustained supplier to Pakistan’s program. They depict a single supplier dispute that Washington treated seriously enough to raise at the ministerial level, and one Ankara appears to have resolved through export controls after initial resistance.
