You're going to actually have to explain what logic you think you're talking about here in order for that claim to stick. Because no, not even remotely.
Well spying is a crime in most countries so saying that it is not a crime until it's detected is just wrong. My point was that crimes are still crimes even if they are not detected.
Spying on a country, in that country, for another country, is absolutely a crime, not ambiguity there. And spying using satellites, many hundreds of miles above controlled airspace, is not a crime - it's not even considered spying. In between those two you get high altitude spying using surveillance aircraft or balloons. It really does fall in this weird "not a crime until detected" grey area.
