Certainly there is Baltic energy dependence on Russia; but it is far from clear what it means. While the energy discourse is highly securitized, it is worthwhile to look at it from another, namely economical perspective:
The article argues that the dependence cited is mutual: gas is traded in a long-term contract market, huge investments in infrastructure result in long-term mutual dependence. Russia as a supplier is especially interested in demand security and is eager to deliver gas on the lucrative European market.
So, exaggerated, historically grounded fears of a Russian supremacy in the Baltic, of political extortions through the “gas weapon” don’t have a basis in the economy-dominated reality. Instead, Baltic States and Russia should cooperate for mutual gain.
