BRUSSELS/ANKARA (Reuters) -Finland and Sweden formally applied to join the NATO alliance on Wednesday, a decision spurred by Russia's invasion of Ukraine, but face objections from Turkey to an accession process that is expected to take only a few weeks.
Neutral throughout the Cold War, Sweden's and Finland's decision to join NATO is one of the most significant changes in Europe's security architecture in decades, not least because Finland shares a 1,300-km (810-mile) border with Russia.
