Re: Spies gonna spy
The question of, "who do we trust enough not to **** us that we don't need to worry about what they are really up to?" is a critical (if uncomfortable) question. If that list is not empty, you need to be spying. The fact that the Germans objected to spying on Italy, which betrayed their government in both World Wars is...touching? hilarious? sad? Allies and friends are not the same thing. You don't spy (much) on your friends.
But if you trust people to be good to you because they say so, your expected lifespan as a nation is quite limited.
