A declaration by Angela Merkel that Germany's attempts to build a multicultural society has failed is feeding a growing debate over how to deal with the millions of foreigners who call Germany home. The chancellor on Saturday Oct. 16, 2010  told a meeting of young members of her Christian Democratic Union that immigrants were welcome in Germany, but needed to learn the language and accept the cultural norms here.
