Final answer:
Finland has the Åland Islands off its southwest coast, which are autonomous and demilitarized with a majority Swedish-speaking population.
Step-by-step explanation:
The country that has the Åland Islands off its southwest coast is Finland. These islands are an autonomous and demilitarized region of Finland but are predominantly Swedish-speaking, which reflects the complex historical and cultural ties in the Nordic region.
The Åland Islands are not considered part of Western-aligned countries such as Greece, Norway, Iceland, the United Kingdom, France, Denmark, West Germany, Italy, Turkey, the Netherlands, Belgium, or Luxembourg. The historical context of the region is also rich with Viking heritage, with reminders of ancient settlements and geographical discoveries, although the Vikings did not colonize the Åland Islands.
