The Bergdahl Deal: A Good Deal?

Looking at the deal from strictly a moral position, I'd have to say it was a good deal. However, I'm not so sure how good a deal it was when you consider (a) the subject, (b) the announcement and (c) the costs.

• The subject is clearly not your average soldier; it looks as though he had walked off his post more than once prior to his final leave taking. 
• Obama's 'celebration' in the Rose Garden assumed that Bergdahl's walking away would not become public, a truly stupid assumption given that the Bergdahl issue had been studied for a few years. 
• While Israel freed over 1,000 Palestinians for one Israeli soldier, the release of five fairly high up and definitely dangerous terrorists seems a high price to pay for someone like Bergdahl.
