US ambassador to the UN is Israel's ambassador to the UN

According to Reuters, Israel's ambassador to the UN has praised US ambassador, John Bolton, as being a part of Israel's team.

Ambassador Dan Gillerman, addressing a New York meeting of B'nai B'rith International, a Jewish humanitarian organization, heaped praise on U.S. Ambassador John Bolton, jokingly describing him at one point as a secret member of Israel's own team at the United Nations.

Not the best kept secret and not the funniest joke if it was a joke at all.
