Both the Irish and Middle Eastern conflicts figure prominently in American domestic politics — yet both have played out in very different ways. The United States allowed the Irish-American lobby to help steer policy toward the weaker side: the Irish government in Dublin and Sinn Fein and other nationalist parties in the north. At times, the United States put intense pressure on the British government, leveling the field so that negotiations could result in an agreement with broad support. By contrast, the American government let the Israel lobby shift the balance of United States support toward the stronger of the two parties: Israel.

This disparity has not gone unnoticed by those with firsthand knowledge of the Irish talks. In a 2009 letter to The Times of London, several British and Irish negotiators, including John Hume, who shared the Nobel Peace Prize for the Belfast Agreement, criticized the one-sided demands imposed solely on Hamas. “Engaging Hamas,” the negotiators wrote, “does not amount to condoning terrorism or attacks on civilians. In fact, it is a precondition for security and for brokering a workable agreement.”
