This sounds much like the prophecies of Fred Phelps in which he presumes that soldiers killed in America is due to a lack of Christian values, or tsunamis killing millions is because God hates Indonesia.
The Pope also made a few other unintelligent statements:
The pontiff's comments to visiting bishops from Canada echoed his statements last month to members of the Pontifical Academy of Social Sciences, when he said that a lack of true love was behind an increase in failed marriages and a decrease in birth rates in much of the developed world.Apparently the Pope hasn't gotten the word that it doesn't take a belief in a sky god to be a good person and love someone else. Perhaps he's also ignorant of the fact that (at least in America) the rate of failed marriages is highest amongst Christians.
Benedict has spoken out several times in favour of large families and called for legislation to help support families with children.Not everyone wants to continue overpopulating the world because God got distracted and hasn't retracted his "be fruitful and multiply" commandment.
