you are correct that it is better for the next Pope to be from Africa or South Asia
I was discussing this on another forum and a friend there suggested that a US Pope may be the answer to be a boost for the Church in the US. With all of the issues concerning the lavender mafia and how they corrupted the Church in the US, including my own Diocese of Rochester with Bishop Clark, it would be better that the next Pope comes from somewhere else, possibly Africa or South Asia. I have issues though with one of the leading candidates, Cardinal Peter Turkson from Ghana. In October 2011, he advocated for "the establishment of a ‘global public authority’ and a ‘central world bank’ and has come out in favour of a Robin Hood-style tax on large financial transactions." That's socialist and violates national sovereignty.
The end facts are that whoever we want, God has a way of giving us a surprise! I was rooting for CArdinal Ivan Dias last time, but have been very pleased with Pope Benedict
