UN Resolution 181 was adopted by a single vote.

Error detected

The claim asserts that UN Resolution 181 was adopted 'by one vote.' The official recorded vote was 33 in favour and 13 against — a difference of 20 votes. The resolution exceeded the required two-thirds majority (31 votes) by 2 votes, not 1.

Omissions

• The speaker conflates Resolution 181 with an earlier procedural vote. In the UN General Assembly's Ad Hoc Committee on Palestine, a partition proposal was reportedly rejected by a narrow margin on 25 November 1947 (25 to 19 with 12 abstentions), but this was not the final Resolution 181 vote.
• The 'one vote' narrative is a persistent historical myth, often linked to lobbying efforts that allegedly swung a handful of delegations in the days before the vote, but the recorded tally shows a clear 20-vote margin.
