The Bergdahl Swap

It seems that conservatives spent a lot of time accusing the Administration of weakness for not getting Bowe Bergdahl back from the Taliban, but as soon as Obama did that, they began talking about Bergdahl being a deserter (which they could well have known beforehand) and about Obama's perfidy in freeing five Taliban from Guatanamo. For heaven's sake, I would think any excuse for getting prisoners out of Guantanamo would be worthwhile. But here's my question: Why doesn't Obama talk about this? Gosh, why must he be so sniveling. All he has to do is say, Hey, you guys wouldn't shut up about this and about my weakness in not getting him back, for years. Now that I've done what you asked, you're attacking from the other angle. It just seems so obvious. I also would like to know about these five "Taliban." Why have they never been tried? No evidence, maybe? Or maybe they've been tortured and thus there's way of trying them? What's the story, news media?
