No matter what we do, those of us in our 20s can't seem to measure up to the Greatest Generation. That bygone nation of joiners, providers and world-beaters, in the standard story, puts to shame today's sad assemblage of narcissists and whiners. Gone are the days when the United States, stung by a Japanese sneak attack, rose up to shrug off the Great Depression and cohere into a fighting force of Riveting Rosies and Private Ryans. Political scientist Robert Putnam called our grandparents "the long civic generation."

Back in January, Brazil's newly appointed minister of science and technology, Roberto Amaral, suggested in a radio interview that his country had nuclear ambitions. "Brazil is a country at peace, that has always preserved peace and is a defender of peace, but we need to be prepared, including technologically," he said. "We can't renounce any form of scientific knowledge, whether the genome, DNA or nuclear fission." It was hardly a Kim Jong-Il-caliber nuclear tantrum, but it did cause a stir. The comments were roundly condemned and a flurry of clarifications followed.
