I honestly can't tell if this is sarcastic or not. Are you saying that you believe ethical practices are so vastly different across arbitrary distinctions like state borders?
Well, your government ostensibly has an obligation to protect your interests, while other state governments have no such obligation.
You can certainly argue against the ethics of any spying, but it should be abundantly clear that a government and its agents have a duty to its citizens that is greater than its duty to the citizens of other sovereign nations.
That's kind of ignorant of the fact that such a mentality starts breaking down a system of trust and confidence that can lead to major cracks in economy and retaliatory actions. It is never a good rule to simply play a game that only has one rule, that everyone is allowed to cheat.
