A quick Google of Quakers and anti-semitism pretty well exposes their position on Israel and Jews. This from an article in the Wall Street Journal:

"The Quakers began to take a fervently pro-Palestinian stance in later decades. In 1973 the AFSC called for a U.S. embargo on arms and other aid to Israel, and in 1975 adopted "a formal decision to make the Middle East its major issue." It opened an office in Israel, installed specialized staff members at offices in the U.S., and began advocating for Palestinians in Israeli and international courts. The AFSC treads dangerously close to outright anti-Semitism and "replacement theology," the idea that Palestinians were the "new Jews," displaced and downtrodden."
