The Congressional Research Service credits the Exon-Florio Amendment (CFIUS's investment veto) to the 1987 Fujitsu–Fairchild bid, not the Toshiba-Kongsberg submarine scandal

The 1988 Exon-Florio Amendment — the statute that gave the Committee on Foreign Investment in the United States (CFIUS) its power to recommend blocking foreign acquisitions of US firms on national-security grounds — is popularly narrated as "America's answer to Toshiba selling out to the Soviets," folding it into the claim-toshiba-machine-sold-ussr-submarine-quieting-tools scandal that dominated 1987 headlines.

The Congressional Research Service's own legislative history of CFIUS assigns the impetus elsewhere: "The proposed sale in 1987 of Fairchild Semiconductor Co. by Schlumberger Ltd. of France to Fujitsu Ltd. of Japan touched off strong opposition in Congress and provided much of the impetus behind the passage of the Exon-Florio provision." The report does not connect Toshiba-Kongsberg to Exon-Florio at all. The load-bearing fear was a foreign takeover of a US semiconductor maker — an investment threat — not the export-control breach that the submarine scandal represented.

This is a myth-ledger candidate in the same shape the vault already tracks: a dramatic, memorable incident (spies, quieted submarines) absorbs causal credit that the record assigns to a duller, more consequential one (a chip-company acquisition) — the recurring pattern named in myth-perceptrons-book-killed-connectionism, where the vivid Perceptrons book eats credit owed to slower, structural causes. The claim rested on a single Tier-2 source pending a second independent account of the Fujitsu–Fairchild episode (question-corroborate-fujitsu-fairchild-exon-florio-trigger); that corroboration arrived 2026-07-18 — claim-graham-marchick-2006-corroborate-fujitsu-fairchild-exon-florio-trigger and its companion notes on the legal mechanism and the second independent silence on Toshiba — moving this claim to budding. The question's "both/and" sub-thread (whether Toshiba-Kongsberg still warmed the general political climate) remains open.

The Fujitsu–Fairchild block was one branch of the late-1980s US "Japan panic"; the other branch — a DARPA/ONR funding surge inspired by Japan's Fifth Generation Computer project — is what carried commercial neural nets through the AI winter, including claim-nestor-inc-commercialized-neural-nets-through-ai-winter (whose Ni1000 chip was DARPA/ONR-funded and built by Intel, itself a Fairchild spinout).
