"When exactly did the government threaten Snowden?"

When it punished Bradley Manning the way it did.

The government doesn't need to make a direct threat, the existing cases are enough to do that.

"is the government not allowed to try and convict people based on the established law of the land"

Of course it is. But there are several cases where the government chose not to.

"I am also curious as to how the government is responsible for Snowden fleeing to Moscow"

If the only place Snowden feels safe is Moscow (because the risk of extradition there is much lower than somewhere else), that's where he is going to go! And if he has something that may be interesting to the Russian government, well, isn't it just lucky...

Bradley Manning was subject to military law and treated accordingly. Do you have evidence he was treated unlawfully? And if not, why would he be exempt from the law?

Snowden was subject to civilian law, so far as I am aware, so he would not be able to draw on Manning as an example.

"Safe", in your world, appears to mean "free from the long arm of the law."
