I think, Sweden is Europe's most successful country in the field of resource management and system engineering. The Gripen program is the clearest indication of this.
In France, both with the policies of De Gaulle, they have a conservative defense industry structure and must have a global voice. Therefore, they are not very successful in resource efficiency. Remember the process of building an aircraft carrier.
The industrial structure of Germany is much more decentralized than the two examples. But this situation combined with the political shift caused by the decrease of the threat factors on Germany, the country has reached a level that threatens defense projects. Today, Germany has the lowest level of military capacity and combat readiness compared to the economic power it has.
That is why, if France re-exit from the common warplane program(like EF), it will be a very difficult process for Germany.
ps: Thank God, we got rid from one of the troll.
