What has happened in the last three years can be summed up, in terms of its short-term and hypothetically long-term consequences, as radical change, what the Anglo-Saxons call, as maritime peoples that they are, “sea change”. Radical change also and above all affects the maritime economy. From the new obligatory routes to the return of the logic of power in trade and in the design of global supply chains. Italy and its maritime economy (and not only) find themselves in the middle of the vortex that goes far beyond the Mediterranean, even extended. From maritime traffic 62% of imports and 95% of raw materials continue to arrive, with energy materials in further growth. It is the means for 50% of exports. In a scenario that will however be more dangerous and that (re)discovers Cold War supply-chain solutions. Italy’s naval commitment is growing in the Indo-Pacific, in the Gulf of Guinea and in perspective in the Arctic. Closer to home, our European location is decisive for the future, but let us not forget that a few dozen miles from our shores there are some “bombs” ready to explode, not least the demographic one.
