It's beautiful to see a prominent European who gets it! Although, snopes does point this out about the article as posted:
A number of readers fluent in German have pointed out that the English translation in circulation contains a passage that wasn't part of the original article; namely, "Even as it is uncovered that the loudest critics of the American action in Iraq made illicit billions, no, TENS of billions, in the corrupt U.N. Oil-for-Food program." The translation also increases the number of deaths due to Saddam's murder machinery from 300,000 to 500,000.
