If you're looking for evidence that the Vatican is a political rather than a moral entity, you need look no further than this (article in German).
Vatican: Torture Worse Than September 11th
The abuse of Iraqi prisoners by US soldiers is, by Vatican lights, a greater blow to the United States than September 11th. Vatican Foreign Minister Archbishop Giovanni Lajolo told the Italian daily "La Repubblica" that the abuse scandal fuels the hatred of Arabs for the west and, above all, Christianity. (...) The torture scandal makes it even more important that the UN intervenes in Iraq and the US gives authority to Iraqi's as quickly as possible.
It's worth noting that Archbishop Giovanni Lajolo seems entirely preoccupied with political consequences of the two acts and with advancing the Vatican's political agenda (strengthen the UN, weaken the US). Nowhere does he evidence the slightest concern for the immorality of killing more than three thousand innocent people.
The report is detailed and hard-hitting and should put paid to any notion that such abuse is typical or that the military is attempting a coverup. It won't, but that's just politics in an election year (and the press running with the narrative they prefer).
If rumors of child abuse at Abu Ghraib turn out to be true, I tend to favor this suggestion, not just because it is appropriate (assuming a very high standard of proof is met) but because of what would likely follow.
In the immediate aftermath, the perpetrators of such heinous acts would be justly condemned by pretty much everyone. The European political class (and much of the American left) would, with their typical hyperbolic flair, go much further -- breathlessly placing them on the chart of historical evil-doers somewhere between Hitler and Pol Pot (though still well below President Bush himself).
Once the offenders were sentenced to death, however, the chattering classes would be required by canon to lionize them as heroes (see: Mumia).
One can only hope that such a rapid transition from "evil incarnate" to "poor, innocent saints" produces enough cognitive whiplash to snap a few necks.
