President Truman had the CIA train over 3000 Cuban exiles to overthrow Castro. Before the invasion, Kennedy took over office and approved it. The invasion failed miserably. In under 90 hours, over 2000 of the exiles were captured and the rest were killed. Kennedy denied to give them air support because he didn't want any US soldiers involved because it would start a war with Cuba and possibly provoke the Soviet Union. President Kennedy had the captured exiles released for a price of food and resources.
<u><em>Native Americans</em></u> and <u><em>Europeans</em></u> were great explorers in the 1490's. <em>Europeans</em> adventurers came to a continent that was an unknown place to them. They saw it as an entirely new territory, with new species to discover. They met new people with surprising ways of living and a totally new culture and beliefs. <u><em>Native Americans</em></u> also arrived at different times, over several thousands of years. They traveled from Asia on foot or by boat, crossing the Bering Strait. Their explorations took them through icy landscapes, deserts, forests, swamps and along the coastlines. After some time, these <u><em>native American</em></u> explorers spread out over the entire continent, until the territories of Patagonia, in the extreme south. Adventure and conquest of new land was one characteristic that <em><u>Europeans</u></em> and <u><em>native Americans</em></u> had in common at that time.
