In 2009, Barack Obama was inaugurated as the first African American to be President of the United States. Two years later, Osama Bin Laden, perpetrator of 9/11, was found and killed. On December 18, 2011, the Iraq War was declared formally over once the troops had pulled out. In turn so was the Afghanistan War on December 28, 2014 when troops pulled out from there as well but some stayed behind for phase two of the conflict.
