Sarah Stern of the Endowment for Middle East Truth surveys the alarming extent of Islamist influence at all levels of U.S. education:

From Harvard Yard to kindergarten classrooms, Saudi extremists have launched a sustained campaign to influence young American minds. These proponents of Wahhabism, a radical Islamist ideology, understand that wars are not fought on the battlefield alone. Indeed, sometimes the most powerful weapon is the idea.
For years, while other philanthropists were busy endowing buildings, the Saudis have been working assiduously to influence the content of what is taught. This includes endowing chairs and creating textbooks. Armed with petrodollars, the Saudis, as well as the United Arab Emirates and other oil-rich Arab nations, have been flooding U.S. schools with approximately $100 million over the years.
