"Questions will be raised about Snowden’s mental balance. Also propaganda."

Why? Is it not a fair question to ask whether the guy who is the single source of all the revelations might not be playing with a full deck? The guy who said "they have a spirited commitment to free speech and the right of political dissent" about Red China? Wouldn't it even be the most Occam-compliant assumption, unless your anti-American prior is so strong you automatically grant credibility to anyone who speaks against the US government?

"Snowden will be called a defector. Also propaganda."

Isn't that technically what he did?

defect 2 |diˈfekt| verb [ no obj. ] abandon one's country or cause in favor of an opposing one

(Biases on the table: I'm biased against people who defect from the US to communist countries.)
