While discussing American public opinion toward Israel, scholars, journalists, commentators and politicians often confuse opinions on Israel with opinions on the Israeli-Palestinian conflict, and views of the state and the people of Israel with opinions on the Israeli government. They frequently use the distribution of responses to a question pollster have asked about sympathies for Israel versus the Palestinians, and they primarily cite results from the Gallup Poll and the Pew Research Center. These sympathy questions measure attitudes toward the Israeli-Palestinian conflict, not opinions on Israel. This study focuses on American attitudes toward several key bilateral dimensions of US relations with Israel. It presents and analyses long-term trends based on numerous national public opinion polls conducted in the United States from 2000 to 2020. The first part explores views of Israel, perceptions of Israel as a US ally and levels of American support for Israel. The second part presents data and analysis of general views of Israel among several groups including Republicans and Democrats, American Jews, Christian Evangelicals, Hispanics, and African Americans. The final section explores views registered in 2020 by gender, race, age, education, party, and ideology. Since 2000, between two-thirds and three-quarters of Americans have held highly stable favorable views of Israel. They have considered Israel a close US ally and thought US support for Israel has been “adequate” or even “too little.” Socio-demographics, however, expose gaps among parties and groups.
