Russia warns of nuclear deployment if Sweden and Finland join Nato

Deputy chairman of Russia's Security Council, Dmitry Medvedev on Thursday said that Russia will be forced to strengthen its forces, including deploying nuclear weapons, if Sweden and Finland were to join Nato.

One of Russian President Vladimir Putin's closest allies warned Nato on Thursday that if Sweden and Finland joined the U.S.-led military alliance then Russia would have to bolster its defences in the region, including by deploying nuclear weapons.

Finland, which shares a 1,300-km (810-mile) border with Russia, and Sweden are considering joining the Nato alliance. Finland will make a decision in the next few weeks, Prime Minister Sanna Marin said on Wednesday.

Dmitry Medvedev, deputy chairman of Russia's Security Council, said that should Sweden and Finland join Nato then Russia would have to strengthen its land, naval and air forces in the Baltic Sea.

Medvedev also explicitly raised the nuclear threat by saying that there could be no more talk of a "nuclear free" Baltic - where Russia has its Kaliningrad exclave sandwiched between Poland and Lithuania.

"There can be no more talk of any nuclearfree status for the Baltic - the balance must be restored," said Medvedev, who was president from 2008 to 2012.

"Until today, Russia has not taken such measures and was not going to," Medvedev said. "If our hand is forced well... take note it wasn't us who proposed this," he added.
