You don't need to exploit the Dutch to have a great game as Sweden. I made Svea Rike - so your first goal is to go Fascist and had a game where I:
(in order)
Took Norway and Finland
Took England
Took Leningrad and Moscow drove to the Urals and forced a Soviet surrender
Took Turkey, the Middle East, Egypt, Ethiopia and most of the Sudan
Took British Raj
At this point it was 48 and I didn't really feel like invading Australia, China and the US since the tech tree was about done so I just declared victory and finished. Sweden is a great game because you really are on a razor's edge with manpower. I never really solved the naval issue. I used BC/CA/CL to great effect but a lot of them got sunk in 45 when I ran into an advanced British CV force (level 4 carriers - no idea how the UK was building them in Africa). But you can get a good enough navy to harass the British and clear an invasion zone.
