George W. Bush was the 43rd president of the United States and a Republican. He came into office after a highly disputed race with Vice President Al Gore, who actually won the popular vote but Bush won the electoral vote. In 2004 he managed to win both the popular vote and electoral vote.
Early on in his administration, the World Trade Center and Pentagon were attacked in an infamous terrorist attack known as 9/11. Bush responded by launching an invasion of Afghanistan to overthrow the Taliban and al-Qaeda. The war is currently being fought and is now the longest war in American history. Unfortunately, the leader of al-Qaeda, Osama in Laden, was never captured although he was eventually killed during the administration of Barack Obama.
War was also fought in Iraq during his term based on accusations of Weapons of Mass Destruction. Although Iraq's dictator, Saddam Hussein, was overthrown, no evidence of WMDs were ever found. The conflict became the second longest war in American history and ended in 2011.
