Cal Thomas: “[O]n the 70th anniversary of D-Day, a lot of people are clueless about central elements of the Allied invasion of the European continent on June 6, 1944. The American Council of Trustees and Alumni (ACTA) has released the results of a survey, which finds only slightly more than half (54 percent) of those who took a multiple choice quiz knew that Dwight D. Eisenhower was the supreme commander of Allied forces on D-Day. Fewer than half knew Franklin Roosevelt was president and 15 percent identified the location of the landing as Pearl Harbor, not beaches named Utah and Omaha. One in 10 college students were among those giving the wrong answer. … Someone should ask a question of the aging veterans who are likely visiting Normandy for the last time this weekend. If they could have foreseen what America would become and how little their descendants know, or care, about their sacrifice, would they have done what they did? They probably would because of their character. I’m not sure the same could be said of too many of their progeny.”
