UNITED NATIONS — Efforts by the Trump administration to marshal a muscular international

response to Iran’s crackdown on anti-government protesters appeared to backfire on Friday,

as members of the United Nations Security Council instead used a special session called by the United States

to lecture the American ambassador on the proper purpose of the body and to reaffirm support for the Iran nuclear agreement.

It was an afternoon of high diplomatic theater that began with a passionate denunciation of Iran’s “oppressive government” by

the American ambassador, Nikki R. Haley, and ended with the Iranian ambassador delivering a lengthy history of popular revolt in

the United States — from the violent demonstrations at the Democratic National Convention in 1968 to the Occupy Wall Street protests in 2011.
