The Franco-German Armaments Cooperation. An Impossible Agreement?
In the Aachen Treaty in 2019, Germany and France agree to deepen their "common program in defense matters" and to pursue a common vision in terms of arms export. These are the preconditions that will help consolidate a culture of common armed forces, common interventions, and European defense industry.

Although the bilateral arms cooperation has been intense for a long time many major projects failed or caused considerable problems. The new "exceptional projects" FCAS (future air warfare) and MGCS (future ground warfare) are at an early stage, are characterized by ambitiousness and pose a certain number of questions. Among these, the respective role of the arms industry in the political process of both States and the correlated question of arms export hold a prominent position. The points of view of France and Germany could not be more different. Also, the strategic directions relating to the military capacity of action and intervention which the systems are supposed to facilitate, do not coincide.
The Aachen Treaty follows the objective to provide the necessary means for France and Germany to be regarded as the forerunners of the European ‘strategic autonomy’. To achieve this goal however three challenges must be overcome: the differences of the arms industry’s role must be tackled and overcome. Therefore, Berlin and Paris need to agree on the role of Europe or the European Union, more specifically, with regard to defense. This requires a public discussion on strategic questions within and between the two countries, which is currently unsatisfactory.

The widespread use of drones observed in Ukraine—both in terms of the scale of the fleets deployed and their omnipresence in the operations of both belligerents—appears to meet the conditions of a genuine military revolution.
The Hunt for Economic Security: The Role of Navies in Deterring Threats to the Maritime Economy
The maritime domain is currently faced with a wide variety of threats, such as climate change, economic warfare, shadow fleet operations, protection of critical infrastructures, and illicit activities ranging from illegal fishing to piracy. Navies suffer from inherent limitations when deterring threats to the global maritime economy: their global presence and permanence limits their credibility in terms of deterrence, their focus usually set on immediate deterrence, implementing deterrence by punishment in and from the naval domain is difficult and costly.

The Franco-German Brigade and the Revival of European Defense
One thing has been clear since Donald Trump's return to the White House: the very existence of the European unification project is threatened. Unless it develops a sovereign defense policy to counter the war in Ukraine and the weakening of American security guarantees, the European Union will continue to see its internal cohesion and external attractiveness wane.
