That's what I've been asking. Thing is the $ didn't need him along and any extra special passenger wouldn't have need him along. It comes down to who he HAD to meet face to face without the NSA snooping in and that person/s couldn't be witnessed coming into the country or any whisper of seeking an audience. Whomever he was wheeling and dealing with had to be met outside US borders. With that, it's obvious it wasn't to benefit the US.
Question for you:
If the US proposed a swap for Bergdahl as a cover for springing the fab five jihadis, and cash, just to be helpful, would you buy it if you were them?
The only guy that could credibly make that overture (its not a swap, because Bergdahl’s almost certainly a traitor (he’s alive)) is either Jarrett or Obama himself.
Who would you trust with that deal?
And moreover, why would you do it if you were Obama? What do you gain by doing it?
