But it's not only a conspiracy theory from writers living abroad...
What do you say about what Stephen Walt and John Mearsheimer said about that??
Here is an example:
"that the US has been willing to set aside its own security and that of many of its allies in order to advance the interests of Israel, that Israel is a liability in the "war on terror", that the biggest Israeli lobby group, Aipac (the American Israel Public Affairs Committee), is in fact the agent of a foreign government and has a stranglehold on Congress - so much so that US policy towards Israel is not debated there - and that the lobby monitors and condemns academics who are critical of Israel.
"Anyone who criticises Israel's actions or argues that pro-Israel groups have significant influence over US Middle East policy," the authors have written, "...stands a good chance of being labelled an anti-Semite. Indeed, anyone who merely claims that there is an Israeli lobby runs the risk of being charged with anti-Semitism ... Anti-Semitism is something no-one wants to be accused of." This is strong stuff in a country where - to quote the late Edward Said - the "last taboo" (now that anyone can talk about blacks, gays and lesbians) is any serious discussion of America's relationship with Israel."
