 The end of the war cancelled the Franco @-@ British plan to send troops to Finland through northern Scandinavia . Some authors would suggest that the official statement by Sweden , Norway and Denmark of February 1940 , declaring they would not allow British troops to use their territories on their way to Finland , was a factor in Finland 's decision of starting peace talks with Russia . One of the major goals of the projected Franco @-@ British operation had been to take control of northern Sweden 's iron ore and cut its deliveries to Germany . For this reason it was also a major factor in the launching of Operation Weserübung , Nazi Germany 's invasion of Denmark and Norway .
