Quotes

 * No one in Finland aspires to occupy Petrozavodsk, but many Finns, but not parliamentary parties, speak about their desire for a return of the territories Moscow occupied. Helsinki officials know that Russia isn’t about to give these areas back and that, if it did, it would cost the Finns enormous amounts of money to bring those areas up to Finnish standards.
