Why did Obama fire 9 Generals in 2013?

WHY IS IT THAT PRESIDENT OBAMA HAS LITTLE PROBLEM FIRING MILITARY COMMANDERS THAT HAVE A LIFE LONG HISTORY OF HONORABLY SERVING THE NATION WHILE AT THE SAME TIME REFUSING TO FIRE SOME OF HIS POLITICAL HACKS WHO HAVE REPEATEDLY LIED TO THE AMERICAN PEOPLE?  THE ANSWER IS REALLY QUITE SIMPLE---HIS HACKS TOW THE MARK AND WILL ALWAYS SUPPORT THE PARTY LINE, WHILE THOSE LEADERS IN THE MILITARY PUT THE INTEREST OF THE NATION AND THE MEN THAT SERVE UNDER THEM FIRST.  PARTY AFFILIATION MEANS LITTLE TO THESE COMMANDERS.  FORMER SECRETARY OF DEFENSE SPEAKS TO SOME OF THIS IN HIS NEW BOOK.  WITH OBAMA ITS DEMOCRATS FIRST AND AMERICA SECOND.
