LA Times article:
"It has been an article of faith of Republican and Democratic administrations for five decades that America should be deeply involved in the Middle East to help protect
Israel, to safeguard sources and shipments of oil, and to maintain peace in a region beset by constant tumult.But a Pew Research Center poll this month found that 2 out of 3 Americans believe the United States should be less involved with leadership changes in the Middle East. Fewer than 1 in 4 said it should be more involved. Some 57% said it was more important to have stable governments in the region, even if that meant less democracy."
"To be sure, some Americans remain deeply committed to a fully engaged foreign policy, including advocates for improved trade, human rights, a strong defense and allies with strong ties to the United States, such as Israel. Their supporters lobby on Capitol Hill and provide important political and financial support to candidates.
But polls show the issue is not a high priority for most voters
