I've never seen that before, how true. Not to take anything away from WW2 vets ,but I think our military today is very competent and up to the task. The difference being we are so prosperous a country that the country functions the same whether in war or peace. During WW2 there was rationizing, food drives, scrap drives etc. that are not necessary today.
A former North Vietnamese General Tran Van Tra wrote in a book that they were ready to surrender if there was one more day of American bombing raids over Hanoi. He also wrote that after the TET offensive, after American troops thoroughly defeated the NVA, he was ready to throw in the towel again until he heard Walter Cronkite declare on the news that it was a defeat of the Americans. He then decided to hold on because he knew the American public would soon give up.
