I would suggest an international conference of the USA, UK, Sweden and Russia on Edward Snowden, Julian Assange, Sarah Harisson, and Bradley Manning.
The best solution would be to send them to live to the North-Eastern Siberia, to Yakutsk or Krasnoyarsk regions, for, say, 10 years. During imperial period such an exile was a punishment in itself. At the same time they would be safe and free. The climate is very cold, but healthy and beautiful. It is another world. Everybody is happy.
Life itself suggests it. Edward Snowden is already almost there. They could work there as school teachers of English language and literature, and IT education.
After ten years emotions would calm down and the situation will be more clear.
