Germany's foreign minister warned on Monday Aug. 6, 2012 that arguments about European policy are taking on a "very dangerous" tone as worries mount about the future of the euro. Guido Westerwelle didn't specify who his comments were aimed at. But they came after Italian Premier Mario Monti warned over the weekend of tensions that "bear the traits of a psychological dissolution of Europe," and a regional official in a German governing party said Greece must leave the euro this year.
