What Sweden would need to sustain a major North American colony

What if Sweden successfully established a large colony in North America?

Sweden would probably need Norwegian ports and population in a stronger Scandinavian union, producing major changes in both North American settlement and the Baltic balance of power.

A Swedish colony occupying the territory of the thirteen colonies is considered viable only with a much stronger Scandinavian base. Control of Norway would provide Atlantic ports and a better starting point for westward expansion, while Denmark would add population to the Sweden-Finland and Norway combination. Establishing those colonies before the British implies an early-sixteenth-century departure from actual history, before the Thirty Years' War. The resulting overseas wealth could also strengthen Sweden's position in Europe, with a speculative collapse of the Tsardom of Russia after a confrontation and greater pressure on Ireland. English naval strength and Scotland's links with the Danish monarchy complicate any further expansion into the British Isles. A still earlier alternative beginning in 1066 imagines closer Anglo-Scandinavian ties eventually producing an even larger union, but the consequences remain open.
