You should look to a map of Europe before and after WWII. When a nation wages offensive war and loses, it can lose territory. At the end of wars borders are often reconfigured. The areas are "disputed" because there never was a Peace Treaty signed. Borders are formed as part of Peace Treaties, not armistices. The lines after fighting has stopped due to a cease fire are temporary until treaties are negotiated. If you think that the "right of conquest expired before 1948" check the maps of Europe, Asia and Africa before and after WWII.
