The prime ministers of Nordic countries rejected Wetterberg's proposal unanimously, claiming that cooperation between Denmark, Norway, Iceland, Sweden and Finland is already very close and fruitful.

Wetterberg explains in his new article that Nordic countries should not create a union because of economic considerations, because they would be small on the scale of the world even if they were together. However, says Wetterberg, they would have more influence in organisations like the UN and OECD.

Wetterberg also finds that the atmosphere of a union can already be felt in the area of the labour market and business in Nordic countries. Many Finns work in Sweden and vice versa, the inflow of labour from neighbouring countries to Norway has increased in the last 20 years and workers are commuting between Southern Sweden and Denmark every day. The scientist mentions Nordea, Statoil, Stora Enso, Fortum, Schibsted, etc., as examples of companies.

The main areas of activity of the possible federal state would be foreign and security policy, economic policy, science, labour market and legislation.
