It failed to stop Jimmy Carter from selling F-15 Eagle fighters to Saudi Arabia in 1978, or to prevent Ronald Reagan from supplying AWACS reconnaissance planes to the Saudis three years later. And its 1991 battle with President George H.W. Bush over the linkage of US loan guarantees for Israel with Prime Minister Yitzak Shamir’s support of the 1991 Madrid peace conference – one of Bush’s key legacies – ended in defeat.
事实上，尤其当事关国家安全时，美以委员会从未战胜过美国总统的坚决反对。它未能阻止卡特1978年向沙特出售F-15鹰式战斗机，也未能阻止三年后里根将预警侦察机出售给沙特。1991年委员会与乔治·H·W·布什总统就美国以提供贷款担保换取沙米尔总理对1991年马德里和会的支持之争（也是布什最关键的政策之一）同样也以失败而告终。
