In 1982, Sheila helped to organize the National Emergency Committee on Lebanon in response to the Israeli invasion.

The Emergency Committee had an office in midtown and three staff people: Sheila, Nubar Hovsepian (then the Political Affairs Officer for the UN Conference on the Question of Palestine) and Stuart Schaar (a history professor at Brooklyn College).

The Emergency Committee was a broad coalition established on June 24 in opposition to the Israeli invasion, whose first action was organizing a demonstration against the invasion in New York on July 10.

The coalition included diverse voices in an effort to shift the debate:

A rabbi and two Christian clergymen from the New York area yesterday jointly denounced Israel’s invasion of Lebanon and called for the immediate and unconditional withdrawal of Israeli military forces. … The forum was a news conference held by the newly formed National Emergency Committee on Lebanon. The conference was held at the United Nations Church Center at 777 First Avenue.

… a July 1982 leaflet prepared for a rally, sponsored by the National Emergency Committee on Lebanon, to demand that Israel get out of Lebanon and for an end to American arms sales to Israel…

The National Emergency Committee on Lebanon, formed in June 1982 to call for withdrawal of Israeli troops from Lebanon, no American arms to Israel and no US troops in the Mideast, also called for US talks with the PLO, the sole legitimate representative of the Palestinian people and American pressure on Israel to end its occupation of Palestinian land. The executive committee included Larry Ekin of the United Methodist Church office at the UN, Sara Flounders of the People’s Anti-War Mobilization, Jawad George of the Palestine Congress of North America, Sandy Pollack of the USPC, Gail Pressberg of AFSC, Stuart Schaar of Jews Against the Israeli Massacre, Mountir Zahr, a supporter of the Lebanese Movement, and Jacki Gelb of MFS.

The committee helped report on the scale of the invasion by summarizing the available body-count figures in “The 1982 Israeli Invasion of Lebanon: the Casualties”, by National Emergency Committee on Lebanon, Race & Class, Vol. 24, No. 4. (Spring 1983): pp 340-342. (SAGE)

It also assembled background information, like “Lebanon, the Palestinians and the PLO: a profile”, by National Emergency Committee on Lebanon, Race and Class, Vol. 24 No. 4, (1983 April) pp 327-334.

It published a booklet “The Human Tragedy in Lebanon”, based on an address delivered at the Riverside Church by Christopher Giannou on August 11, 1982.

It organized teach-ins about the invasion:

AIPAC was dismissive:

Some of these groups were merely new guises for longtime pro-PLO activists. For example, the coordinator of the National Emergency Committee on Lebanon, Sheila Ryan, also heads the Palestine Solidarity Committee, a New York-based group long supportive of the PLO.

This was apparently enough for the city of Portland, OR to open a police file on the committee, although nothing substantive ever came of it.
