It blows up in your face precisely because your "help" is nothing of the sort. You wonder why people despise America when they have suffered under the brutal dictators that you put in power? You expect their thanks for removing them?
Simon, my dear friend.
Is it possible it might have been better to refrain from using the pronoun "you" in the above quote? Just a hint - it might be a tad inflammatory.
Perhaps best to use "a nation" or "one might wonder" instead. Your use of the word personalizes the diatribe and is probably not what you meant to do.
Or I could be wrong.
