Currently (May 11, 2014) the US is not involved in any declared wars, and hasn't been since August, 1945. The only active conflict is the ongoing "war on terror", in which American soldiers and airmen are fighting Islamic terrorists in Yemen, Afghanistan and Iraq.
The US has fought no major wars since Vietnam.
