NEVER, NEVER, NEVER, NEVER, NEVER, EVER, will a defector be sent back to Russia.
(With the single exception of hundreds of Soviet soldiers who wanted to stay in Germany after the war but were sent back anyway).
Because the defectors DON'T WANT TO GO BACK, unless of course, they do.
Same with Mr. Snowden. He will return to America when and if he wants, and not a minute sooner.
And if he does return, I predict it will not be during the time that Obama remains president-alleged.
