Sweden’s ruling Social Democrats said Monday they will review their long-standing policy of military nonalignment, after some lawmakers demanded Sweden apply for NATO membership. This comes after Finnish leaders said they’re considering a plan to end Finland’s long-standing neutrality policy in order to join NATO. In Moscow, Kremlin spokesperson Dmitry Peskov warned NATO against the inclusion of Sweden and Finland.

Dmitry Peskov: “We have repeatedly said that NATO remains a tool geared toward confrontation. It’s not the kind of alliance that ensures peace and stability, and its further expansion will not bring additional security to the European continent.”

Earlier this year, Swedish and Finnish soldiers joined about 30,000 NATO troops in northern Norway near the Russian border for Arctic war games known as “Operation Cold Response.”
