"The fact is, you cannot be a World Power without committing transgressions, sometimes huge transgressions."
Great Powers do indeed commit appalling "transgressions". List a few of the ones committeed by the countryt I am living in, and I wouldn't feel any need to excuse them.
Maybe it's inevitable. Maybe the level of "transgressions" can be reduced, especiallly if the citizens of then great powers concerned refuse to tolerate them.
Equally one could say that you cannot be a small neighbour of a World Power, under siege from that World Power, without committing transgressions.
