@BillRM,
If Snowden became the leader of a country which won their independence from the US, then yes, maybe someday, that country will have a holiday named after him. Purely in the context of your analogy, in the US, it is more accurate to look upon him as Benedict Arnold.
(Getting ready to barricade myself behind a shield in preparation of the coming missiles being thrown my way....) got things to do today luckily.
