Yes, clearly, in relations to his hatred of Israel and his attempts to tie "Jewish influence" to the Pro-Israel Lobby.
Well, the Pro-Israel Lobby is a way for Israel and its friends to influence U.S. politics in terms benefiting the Jewish state. Nothing unusual or sinister about this (I mean, there's the Irish Lobby among many others), but terms such as "Jewish influence" have very unpleaseant historical connotations.
Well, this one is troubling me a little.
Yes, but not to support Israeli policies doesn't mean one's an anti-semite. I, for one, I'm proud of my Jewish ancestry and support Israel's right to exist, while being very critial toward certain longterm aspects of Israeli policies.
I dom't agree there's some automatic equivalence.
