Seriously, it's not:

Many lessons may be learned from the decision of University of St. Thomas President Dennis Dease to uninvite and then invite Desmond Tutu to speak on his campus... Another lesson is about jumping to conclusions without evidence. Tutu's canceled invitation received international notoriety because many thought it was part of a pattern of widespread Jewish pressure to censor Israel's critics. But President Dease demolished that idea. "I was under no pressure from any pro-Israeli groups or individuals, nor did I receive any requests from them to refrain from inviting Archbishop Tutu to speak," he declared. That an esteemed Catholic university leader would feel compelled to make such a public denial is sad testimony to an upsurge of sinister theories about Jewish power in America today.

The beauty of conspiracy theory, of course, is that it takes evidence of disproof and transforms it into proof. It's not even particularly difficult. President Dease says that pro-Israel influence had nothing to do with his decision? That just proves how much control pro-Israel groups really have, because they were able to force him to issue a denial.

A central plank of the Walt And Mearsheimer conspiracy theory has always been that the US attacked Iraq because of Israel. The idea is so stupid that even the sophistication-enamored Obama was moved to unequivocally repudiate it. There's also the small problem of this:

Israeli officials warned the George W Bush administration that an invasion of Iraq would be destabilizing to the region and urged the United States instead to target Iran as the primary enemy, according to former Bush administration official Lawrence Wilkerson. Wilkerson, then a member of the US State Department's policy planning staff and later chief of staff for secretary of state Colin Powell, recalled in an interview that the Israelis reacted immediately to indications that the Bush administration was thinking of war against Iraq. After the Israeli government picked up the first signs of that intention, said Wilkerson, "The Israelis were telling us Iraq is not the enemy - Iran is the enemy."

No problem for the average conspiracy theorist, who will just say that the report is an Israel Lobby lie. But Walt And Mearsheimer are not your average conspiracy theorists. Their solution: Israel talked the US into invading Iraq to set up the invasion of Iran. Of course they did.
