The strongest available evidence is the Wall Street Journal result, whose headline and snippet directly match the claim: 'U.S. Military Prepares to Board Iran-Linked Ships in Coming Days ...' and says the U.S. military is preparing to board and seize Iran-linked oil tankers and commercial ships in international waters. Both supplied X posts independently restate the same claim, and The Kobeissi Letter post explicitly attributes it to WSJ. Confidence is medium rather than high because the run could not fully fetch the WSJ article body due access/tool limits, so validation relies partly on the search-result snippet plus consistent secondary attribution.
