By that token, Europe should have gone to war with the US for spying on its very leaders — Angela Merkel, François Hollande, etc. (The Snowden revelations and the aftermath).

I honestly don't see how the US could spin anything positively on the world stage in that regard, they are by far the worst offender as far as spying is concerned. It's not even funny to compare. And there is documentation that tech/trade secrets from foreign companies aquired by e.g. CIA or NSA was given to US companies — industrial espionage isn't exactly new or surprising, but when conducted by Federal Agencies above any control, responsibility or accountability to the US public, let alone the UN or the world...

Your suggestion is disingenuous at best and, I'm sorry to say so, terribly blind to the reality of the world, wherein the US is certainly not an all around good guy. Especially these days, it's clearly a hostile power to most others. As seen from the EU, at least, I can't speak for other places/cultures. But I hear it's not that great in general.
