Sorry this is pure fantasy. Sweden has not been a major power since the reign of Charles XII. Sweden, like most of Europe, has gutted its military. In a major war with Russia they could expect to last about a week. That by the way is not my opinion. It was the statement of the top Swedish military commander to parliament when asked about the effects of military spending cuts over the last twenty years.
Europe today has become a de-facto military protectorate of the United States.
In Western Europe, only the Brits and the Frogs are capable of sending an expeditionary force.
And that's only because of the speed governors the Russian have on their trucks.
