Given how large Airbus is - playing second fiddle in this way to French is not on the agenda for them. So things may come to pass and France may have to go it alone or try and keep it going with the Spanish ...
I dont want Germany to get involved in Tempest based on their previous Eurofighter behaviour - on anything other than an end user/customer to buy Tempest as an off the shelf product.
Given what Dassualt wants - Germany is better off saving the "development" cash if it is not going to get the technology and use that development money to buy "more Tempests" than they could if they spent the cash on development aswell as manufacturing.
As a side note - the Indians tend be as arrogant and finicky to work with as the French on military development projects - so it is a partnership made in heaven for the both of them?!?!
