You were in the middle of a civil war, what're you going to do about it?

*Can totally unite Scandinavia under one banner in 3 years*

Otherwise, I'll go ahead and arm the Finns, who would refuse to be another country's slave again, puppet Denmark, because it would be SO easy, achieve naval domination of the Baltic Sea, completely cut off the Swede's trade routes, and, if the Swede's wanted to continue poking the colossus, send in a small invasion force to take Stockholm by force.

Germany was weakened by the Great War, not destroyed. Even if the Nords declared war the day the war ended, Germany could've stood against them. You can unite Sweden and, maybe Norway, but the Germans would intervene if any other gains were attempted. 

There is no way a united Scandinavia could already exist in this world, unless Germany pulled a Russia and exploded. 

I tried to offer you advice, and, you did ask "would anyone be opposed to that?" But if you wanna have a little temper tantrum, Daddy Deutschland will go get his belt.
