In 1981, the New York Times covered a PSC protest held adjacent to the annual New York City parade for the foundation of the state of Israel:

In a message from Israel, Prime Minister Menachem Begin appealed to Israel’s supporters not to allow any retaliatory actions against his country for destroying the Iraqi reactor. …

The crowd, which included marchers from 100 groups and thousands who lined the avenue to cheer them, applauded the Prime Minister’s statement.

The appeal was mocked at a counterdemonstration sponsored by the Palestinian Solidarity Committee attended by some 100 people nearby in Central Park . ”The Salute to Israel parade is a salute to racism, colonialism and repression,” said one banner held aloft there. ”Stop U.S. Aid to Israel,” said another. …

The Palestinian rally in Central Park off Fifth Avenue and 97th Street was called ”A Teach-In on Avoiding War in the Middle East.” Sheila Ryan, an organizer of the teach-in, said that her group’s aim was to ”stop the continuing flow of weapons to the Middle East.” She said this included Israel and Arab nations.
