Yes, I agree it's unfair. Pragmatism is not a uniquely USAmerican trait or operating principle, neither is principled behaviour really absent from the USAmerican mythos, I think. I've just been watching a lot of things lately that lionize the American mil/espionage machine and one of the key aspects of its activity is its pragmatism: that is, the argument for doing dirty things, with collateral damage, is that the end justifies the means and "more lives will be saved" etc, etc, etc.

It's certainly fair to admit that the USA certainly didn't create this characteristic, nor that it isn't present, to a certain extent, in the statecraft toolkit of all governments everywhere.
