regard to the integration problems with Arab and Turkish people in Germany has been critical throughout. According to her personal statements, Sarrazin's approach is "totally unacceptable" and counterproductive to the ongoing problems of integration. The term alternativlos (German for "without an alternative"), which was frequently used by Angela Merkel to describe her measures addressing the European sovereign-debt crisis, was named the Un-word of the Year 2010 by a jury of linguistic scholars.
