George W. Bush narrowly won the 2000 presidential election over Al Gore after a Supreme Court decision on contested ballots in Florida. As president, Bush pursued a conservative domestic agenda including tax cuts and education reform but his presidency was shaped by the terrorist attacks on 9/11. Bush launched a "war on terror" including the invasions of Afghanistan and Iraq, though the latter conflict became increasingly unpopular as no weapons of mass destruction were found and sectarian violence rose in Iraq.
