You're opinion and experience do a good job of having a blatant disregard for the facts. I can respect your experience in the field, but that doesn't account for:
1. The fact that there have been several foreign policy failures just as bad as this one.
2. Obama did not lie. He was not on the same page as the rest of the administration who took two weeks to admit it was a terrorist attack.
3. Every President has been responsible for American lives and has lost some on his watch. Just because every death isn't as well documented as this one, it doesn't mean that they don't happen.
Listen, every President tries as hard as they can to ensure the safety of their citizens and preserve the effectiveness of their operations. Do you think any sane man wants to live knowing that they've been responsible for the death of somebody who followed them? Do you think any leader wants to know that one slip up, one tiny movement in the wrong direction cost a life? As far as your experience has got you, you'll never have the opportunity to say that you've EVER experienced the stress and agony that this man has. I don't care if you think Obama is the worst President in United States history, he is still one of the most brave, respectful, and caring individuals in the nation and wouldn't for a second consider letting himself give this job less than 100% of all he's got. So for you to say "A pox on Obama. To support him further at this point is to be a wretched American. No doubt we got 'em, but it still sucks to be one.", well you might as well be 10x as disrespectful and unknowledgable as I am. Comments like mine may shows gaps in knowledge, but comments like yours are the epitome ignorance.
