Christopher Columbus is the explorer who is credited for discovering America. Of course, there were already people living in America at the time who we call Native Americans. There even was a European, Leif Ericsson, who had been to the Americas before. However, it was Columbus' voyage that started the exploration and colonization of the Americas.
During the Vietnam war between 1964 and 1973, the U.S. military drafted 2.2 million American men out of an eligible pool of 27 million.
