What reporting and primary-source statements exist in the NK News, NK PRO, and KCNA Watch archives about changes to U.S.–South Korea intelligence sharing since Unification Minister Chung Dong‑young’s March disclosure of a suspected uranium-enrichment facility at Kusong — specifically: which official U.S., ROK Defense Ministry, and NIS statements address any restrictions; which categories of intelligence (nuclear, missile, conventional, cyber, counterintelligence) were reported as limited; whether there is evidence the U.S. limited sharing to missile-related intelligence only; how South Korea’s independent intelligence capabilities have been described as compensating; and whether there are past precedents of the U.S. curtailing intelligence sharing with Seoul after public disclosures?
