Russia is investigating NATO in the Baltic Sea. This place is crucial

The Øresund Strait ceased to be only a geographical isthmus between Denmark and Sweden. In the reality of Russia's war against Ukraine, it has become 1 of the most crucial points of contact between the Kremlin's war economy, Western sanctions policy and NATO's military security. [ The Cipher Brief](https://www.thecipherbrief.com/sweden-denmark-power-over-russia) argues that Denmark and Sweden have a real geographical advantage over Russia due to the fact that they control both sides of the strait through which a crucial part of Russia's exports of natural materials from the Baltic pass. This is the starting point: Øresund is no longer just a shipping route, but a place where Russian oil, the shadow fleet, NATO's intelligence and deterrence begin to make a single safety problem.
