A survey conducted in the United States revealed a tangible drop in the number of American evangelicals, under the age of 35, who support Israel. "Overall support of evangelicals for Israel will drop significantly in the next decade if the younger generation is not educated to change their views," according to the survey, which was conducted at the request of pro-Israel evangelical leaders. Evangelicals make up the biggest pro-Israel bloc in the US. 58 percent of evangelicals under the age of 35 have shown positive views of Israel, compared to 76 percent of the generation of evangelicals over 65 years of age. Some 2,000 American evangelicals participated in the survey. 66 % of evangelicals under the age of 35 said "Christians should make more efforts to show love and concern for the Palestinian people." While older evangelicals said that the Palestinian people "have no historical right in the land of Israel." Joel Rosenberg, an activist and evangelical author living in Jerusalem and one of the writers of the poll, said that about 41 percent of evangelicals under the age of 35 "have no supportive views toward Israel," compared to only 22 percent of adult evangelicals, which was considered by the initiators of the poll as the most "worrying". Regarding the peace process with the Palestinians, 46% said they did not know whether they would support the establishment of a Palestinian state in the West Bank, while 23% supported such a move. Only 31% said they would oppose it.
