The right for bilingual topographic signs for the regions where Slovene and Croat Austrians live alongside the German-speaking population (as required by the 1955 State Treaty) is still to be fully implemented in the view of some, while others believe that the treaty-derived obligations have been met (see below). Many Carinthians are afraid of Slovenian territorial claims, pointing to the fact that Yugoslav troops entered the state after each of the two World Wars and considering that some official Slovenian atlases show parts of Carinthia as Slovene cultural territory. The former governor of Carinthia Jörg Haider has made this fact a matter of public argument in autumn 2005 by refusing to increase the number of bilingual topographic signs in Carinthia. A poll by the Kärntner Humaninstitut conducted in January 2006 stated that 65% of Carinthians were not against an increase of bilingual topographic signs, since the original requirements set by the State Treaty of 1955 had already been fulfilled according to their point of view.
