Federalism has nothing to do with it, this isn't about Macron but about Dassault and Airbus who are trying to find ways to work together. To make it short Dassaul is the manufacturer picked by France who are the supposed leader of the project but Spain and Germany picked Airbus Defense, now the issue is that because Germany and Spain have picked the same manufacturer Airbus are supposed to have 2/3 of the workload while Dassault are supposed to lead the project, previously the workload was 50/50 with Dassault as the leading manufacturer. Now Airbus wants to impose a lot of things because they can.
This topic doesn't concern Brexit or the EU, it has nothing to do with it. Though it does show how France and Germany can sometimes be idiotic, the reason they started the project is because they have a defense agreement, which has nothing to do with the EU or federalism, they shouldn't add a third country to the project. Now the organization is almost guaranteed to be botched because Dassault's concerns are legitimate, you can't put them in charge and then make sure that they aren't really in charge while still putting their reputation in the balance.
Most of that is quite correct and as usual, you have a very good understanding of the subject.
I have never said anything about Brexit. It has nothing to do it that.
But as mentioned, the article I have read and re-read to check refers to the political aspects.
The project is government funded and Macron is a big advocate.
Merkel is less convinced, but does not want Germany left behind because the UK, Italy and Sweden are collaborating on a parallel project called Tempest.
The article, which is in Flight, a world leading aerospace magazine does state that Macron is driving the project 'in part to push forward with plans for a Sovereign Europe'.
You may not agree, but that is what is being said.
