I do not think the US government would bother to try to prosecute that. It is just not worth the resulting diplomatic drama. I think right now the Obama administration is happy that people are starting to forget about the whole affair. The NSA's mass surveillance program is still on and it seems now accepted as the new normal. Ultimately Snowden has failed. He exposed the program but the resulting outrage was not strong enough to bring it down. In fact, now that the US government got away with this they will probably get even more extreme in future..
