If 15% of Americans are anti-Semetic, that means that 85% are not. The policies of the Bush administration have also significantly contributed to negative views of Jews worldwide, not just in America. Whilst I support Zionism, I think many people have forgot its intentions of creating a self-sufficient Jewish state. The 'Israel lobby' in the United States itself conforms to negative stereotypes about Jews - that certain interests in banking and mass media are swindling the wealth and power of the United States to support Israel. I doubt the original supporters of Zionism - from Herzl to Churchill, ever intended Israel to be dependent on the lobbying work of AIPAC and the ADL in the United States.
