Snowden has revealed a number of things which are true, and which the US gvernment wished not to be revealed. As a consequence the US government is set on locking him up, probably for the rest of his life.

No one denies that the stuff he has revealed is true. No one, so far as I can see, has given any reason to think that any harm has been caused by the revelations, over and above embarassment to those in power in the US.

It's shameful that the only countries which have indicated they are open to giving him asylum are far away from where he is holed up, in Latin America. That's how far we have fallen in Europe, as evidenced by the humiliating episode in which a cabal of countries colluded in blocking overflights of a presidential plane which it was believed might have Snowden on board.
