Going to Russia was the worst idea ever. I'm sure at this point he is completely under Putin's control and will never be a free man again. They have already grabbed all the intel he had and will likely never let him leave.
Just making it look like he wants asylum there now.
Instead of any of it going public it now just goes straight to Russia to be used against the US.
Snowden should have gotten to Iceland or where ever and gotten asylum before he came out with any of it.
Huge opportunity squandered.
