The government-commissioned report found that an arms race in the Baltic region is a likely scenario should Sweden join NATO, but that the risk of a conflict with Russia would decline.
The report, which was seen by news agency TT, has received mixed responses from politicians.
Speaking to Swedish Radio, Liberal Party leader Jan Björklund welcomed the investigation's conclusions. He believes that with Russia’s aggressive posturing towards the Baltic region, Sweden would be safer as a member of NATO.
The report also states that it is unlikely that Russia would attack Sweden alone. Björklund agrees but says that, in a situation where Russia were to attack or threaten others in the region, Sweden, as the geographically largest country in the Baltic, would be dragged into the conflict.
“Only Sweden (being attacked) is unlikely, I agree. However, in a situation where Russia wants to attack or threaten the Baltic States, which is not at all unlikely, more countries in the region would be dragged in...Since Sweden is geographically the largest of the Baltic Sea Forces, we would very likely be drawn into a conflict. It is to prevent this that Sweden should be a NATO member,” Björklund told Swedish Radio News.
However, Stig Henriksson, the Left Party's defense policy spokesperson, completely disagrees with Björklund’s reasoning to join NATO, telling Swedish Radio: “He says that it is unlikely that Russia would attack Sweden. That is the only scenario in which NATO and Article Five would be helpful to Sweden. However, we would risk being brought into a larger conflict with NATO membership and I do not understand how that is beneficial to Sweden’s security.”
