U.S. exits UNESCO (1984)
The Reagan administration pulled the U.S. out of UNESCO, the UN education and culture agency, over what it called anti-Western bias and mismanagement. Washington rejoined in 2003, then withdrew again in December 2018 under the first Trump administration over alleged anti-Israel bias.
UNESCO lost roughly 25% of its budget when the U.S. left in 1984.
The double exit-and-return shows U.S. participation in international bodies has been reversible across administrations.
The GRECO exit follows the same pattern — a withdrawal framed as cost-cutting that a successor administration could reverse.
