Anti-Semitic, what?

Can someone explain to me why claiming, as your own opinion, that the United States and Israel are engaged in an effort to "dominate that part of the world," referring to the Middle East, is anti-Semitic. Let's face it, militarily they pretty much do, although not without facing deadly terrorism and insurgent attacks every day. And what of the difference between that and stating that Israel was behind the 9-11 attacks? How can they be even considered together? Oh, and lastly, while the Washington Post is busy printing the article about Dean's apology, perhaps they ought to consider printing John Conyers' letter calling Dana Milbank a big fucking idiot stooge.
