Did President Donald Trump post a message saying, "Belgium is 2 weeks away from developing a nuclear bomb"? No, that's not true: The message, which appears to mimic a Truth Social post, is fake. A review of his account history found no record of the supposed post. There are no credible reports that he ever shared such a message.
The claim appeared in a post and image (archived here) by the @dogeofficialceo account on X on July 7, 2026. It read:
Trump reacts to the USA's loss to Belgium
This is what the post looked like on X at the time of writing:

The text included in the fake post read:
Belgium is 2 weeks away from developing a nuclear bomb!
Lead Stories manually reviewed Trump's Truth Social account for recent posts containing the phrase "Belgium is 2 weeks away from developing a nuclear bomb!" Lead Stories also searched Trump's Truth -- a website that archives Trump's Truth Social posts -- for the same phrase. No matching posts were found (archived here).
Lead Stories searched Google News (archived here) and Yahoo News (archived here) and did not find any matching reports for "Belgium is 2 weeks away from developing a nuclear bomb." Had the president actually made such a post, major news outlets would have widely reported it.
