Perhaps Snowden was justified in revealing domestic spying programs. Perhaps not.

But Snowden also leaked a lot of information about our legitimate foreign intelligence activities. Spying on foreigners is the raison d'etre of the NSA, CIA, et al. He revealed our methods and capabilities for conducting such foreign intelligence while fleeing into the arms of our adversaries.

He should face trial for this treachery and pay the price. The punishment for treason is death.
