A drop in the bucket, considering Latin America is well over half a billion people in a vast, emerging market. Coke and other US companies make far more than a billion a year in this market alone. The aid you give does end up coming back to you in terms of new markets. As for latin politics, I don't think an American has any grounds from which to criticize. Democrat or Republican? American politics don't matter because the result is always the same. Spend spend spend. War war war. Bully bully bully.
