In response to the mounting tension with Russia, Sweden has been boosting its military preparedness and has sent soldiers and heavy military equipment to its largest island, Gotland, strategically located in the Baltic Sea, just 330 kilometers from Kaliningrad, the headquarters of Russia’s Baltic Fleet headquarters… Sweden has been observing a deteriorating security environment in recent years with repeated Russian incursions into Swedish airspace and territorial waters.
Unlike Sweden, Finland, which shares a long land border with Russia, never stopped investing in its defense capabilities. It recently ordered 64 F-35 fighters, at a value of $9.5 billion, to replace its existing and ageing combat jets. According to Finland’s former Foreign Minister Erkki Tuomioja, Finland “can mobilize a reserve of 280,000 trained soldiers, which no other country in Europe can do.”
In a meeting with Sweden and Finland on January 24 about the worsening security situation in Europe, NATO Secretary General Jens Stoltenberg invited the two countries to join NATO, stressing that each country has the right to choose its own military alliances.
Denmark is deploying four air force fighter jets to the Baltic states and a Danish Navy frigate will most likely be patrolling the Baltic Sea, as a contribution to NATO’s patrolling in the region. This is “a very clear signal to Russia,” Danish Defense Minister Trine Bramsen said.
Russia’s military buildup on the borders of Ukraine and its sweeping ultimatums to NATO on halting further expansion and rolling back its engagement on NATO’s eastern flank is also causing tension in northern Europe. Russia has threatened that if Finland and Sweden — which are not members of NATO but enjoy close ties with the transatlantic organization — join the alliance, it “would have serious military and political consequences that would require an adequate response from the Russian side.”
