Russia has gone on the offensive in the Baltic, warning Denmark that if it joins Nato’s missile defence shield, its navy will be a legitimate target for a Russian nuclear attack. “I don’t think that Danes fully understand the consequence if Denmark joins the American-led missile defence shield. If they do, then Danish warships will be targets for Russian nuclear missiles,” said Mikhail Vanin, the Russian ambassador to Denmark, to the Jyllands-Posten newspaper.
