The euro zone is shakier than its advocates would like you to believe. The True Finns are known for opposing bailout funds for the Greeks and Portuguese; the party increased its representation in the 200 seat parliament from six seats to thirty-nine.
Finland joined the European Union in 1995, and the euro common currency zone when it began in 1999, perhaps seeking a counterweight to their huge, and sometimes belligerent neighbor, Russia. They have not, however, joined NATO as have several of their neighbors with concerns about Russian interference.
