The Via Crucis of John Mearsheimer

John Mearsheimer developed the theory of the Israel lobby because the facts contradicted his Realist theory of international relations. Now the facts are contradicting the very same Israel lobby theory he developed to plug the holes in his IR theory.

It’s difficult to argue that Israel and the Israel lobby control US foreign policy when Washington arrives at an agreement with Tehran:   

• That Israel had no say in;
• Achieves none of Israel’s war aims;
• Is universally opposed by Jewish Israeli leaders across the political spectrum;
• Is met with skepticism by pro-Israel hawks in the US.

Even if the agreement falls apart, it is still the case that Washington has acted in a manner that is hostile to what Israelis perceive as their interests.

“The Israel lobby” is a category of explanation invoked to account for the failure of certain theories to explain US actions (e.g., some Realist IR theories, or the theory that US foreign policy is fundamentally benign in its intentions if not always its actions.)

The problem lies with the theories. They don’t explain what they set out to explain.

John Mearsheimer is a Realist IR theorist, and the most vocal exponent of the theory that 1) Washington acts against US interests in West Asia and in favor of Israel’s and 2) it does so because its foreign policy has been hijacked by the Israel lobby. He readily acknowledges that his IR theory doesn’t explain US behavior in West Asia.

Steve Walt and I, who are both card-carrying Realists, wrote this book called the Israel Lobby and US Foreign Policy. And lots of people over the years have delighted in pointing out, in a “got-ya!” moment, that the Israel Lobby book contradicts our Realist theory. Because the Israel Lobby book says that domestic politics causes the United States to act in non-strategic ways. This is what the Israel Lobby book says. It says that when it comes to Israel, the United States is not behaving in a way a Realist would expect American policy-makers to behave. It’s because of the Lobby; domestic politics. And people expect us, when they level that charge at us, to be defensive and say ‘Oh no, the Lobby book really fits in with our theory.’ But our response is, ‘You’re absolutely correct. The Israel Lobby contradicts my basic theory of international politics.’ [1]

You may notice that Mearsheimer engages in some question-begging here (question-begging in the sense of assuming the truth of what he’s trying to prove in his premise.)  He says “that when it comes to Israel, the United States is not behaving in a way a Realist would expect American policy-makers to behave,” and then adds “It’s because of the Lobby.” An alternative explanation is that the United States is not behaving in a way a Realist would expect American policy-makers to behave because the theory is wrong. Instead, he assumes the theory is correct, and that something else must be going on to obscure its validity. Presto, the Israel lobby theory is born.

The problem, however, is that the Israel lobby theory has as many holes in it as there are holes in the original theory it was designed to plug. That’s evident in the obvious rift that has developed between Washington and Tel Aviv over the question of how to proceed on Iran.

Apart from being an add-on to save Mearsheimer’s IR theory, the Israel lobby theory is also a political tool used by some activists to mobilize support for pro-Palestinian positions by deliberately fostering a misunderstanding that a foreign power has hijacked the US state and that US citizens are paying for wars fought in Israel’s interests and not US interests.

The truth is that US citizens are paying for US wars—and the wars are being fought in the overlapping interests of US billionaires and Israeli colonizers. They may not want to face up to the fact that their government’s conduct is vicious and tyrannical, and may prefer, instead, to see the United States as a fundamentally benign but helpless giant manipulated by an Israeli Svengali, but this is nothing more than a comforting illusion.

The reality is that the domestic billionaire class that shapes US foreign policy goals has set objectives that, for the most part, mesh with the settler colonial project of Israel. Broadly speaking, the overarching US objective is to prevent the emergence of an independent regional hegemon in energy-rich West Asia.

Owing to its cultural, ethnic, demographic, and economic connections with the West (Israel sees itself as part of the West, a Western outpost in the East), and its complete dependency on Western support to survive, Israel is uniquely placed to act as a US janissary—a protector of US interests in the Land of the Five Seas [2] and elite combat force equipped and motivated to assert US interests. Guardian of the interests of great powers in the Arab and Muslim worlds has, from day one, been the role sought by Zionists for a Jewish state. The quid-pro-quo has always been understood as: We look after your interests in the region against those of local forces of independence, and you guarantee our survival.

A troubling aspect of the Israel lobby theory is its resonance with a Nazi theory.  

Hitler did much the same as Mearsheimer in explaining why something didn’t happen that he thought should have happened.  

Mearsheimer says the United States is not behaving in a way a Realist would expect American policy-makers to behave because policy-making in Washington has been taken over by decision-makers who are committed to Israeli goals and Israeli goals are inimical to US interests.

Similarly, Hitler said Germany should have won the First World War and didn’t because Jews penetrated German policy-making circles and took over German decision-making and pursued Zionist goals that were hostile to German interests. How else could one explain, asked Hitler, that no enemy troops had ever set foot on German soil, and still Germany lost the war? In this, Hitler anticipated Mearsheimer’s wondering how Realist IR theory failed to account for US behavior in West Asia. For both, a Zionist take-over offered a ready explanation of failed expectation.

Overlapping interests, not Israeli colonization of foreign policy decision-making in Washington, account for why US and Israeli decision-makers are so often in sync. Occasionally, however, the goals of the two states depart, as they do, now, on Iran. Israel wants to finish off Iran, destroy Hezbollah, and continue its expansion into Lebanon. Washington wants to prevent the world economy from going off an oil- and fertilizer-scarcity cliff, and is prepared to make concessions to Iran that Israel doesn’t like in order to avoid a world-wide calamity.

When US and Israeli interests fail to align, the US asserts its greater strength, and Israel tries to maintain some degree of autonomy by negotiating the terms of its subordination. But it remains, as always, a subordinate state and instrument of US policy. For its part, the US remains, as always, the guarantor of its janissary Jewish state’s survival.
