As the most powerful leader on Earth, a president must wear many hats. And while Chief Executive appears to be the toughest responsibility, considering the state of our economy, I believe that Barack Obama's biggest opportunity to screw things up is when he is donning the hat of Commander-In-Chief. As such, his primary mission is to ensure the well-being of his forces, and by extension, the safety of the country they protect. But recent actions he's taken call the success of that mission into question.
