The first duty of any government is to protect the interests of its citizens. If African politicians took their responsbilities seriously, they wouldn't need to complain about the American government just doing its job. Obama is not the President of the World - he's President of the USA and answerable to his own electorate. If African countries want to solve their problems the answer is in their own hands. Look how Rhodesia and South Africa managed to establish thriving economies when they were cut off by sanctions from the rest of the world.
