So I was wondering how it is possible and what pod is required to have France and Britain to be closer or as close as OTL France and Germany. The pod should be after WWI if possible.
Maybe something like this:
Downing Street Declaration
The 2 November 2010 Downing Street declaration by President Sarkozy and Prime Minister Cameron. The elements of this declaration are as follows.
Defence and Security Cooperation Treaty
The purpose of this is to develop co-operation between British and French Armed Forces, the sharing and pooling of materials and equipment including through mutual interdependence, the building of joint facilities, mutual access to each other’s defence markets, and industrial and technological co-operation.
Nuclear Stockpile Stewardship
Collaboration on the technology associated with nuclear stockpile stewardship in support of both countries independent nuclear deterrent capabilities, including a new joint facility at Valduc in France that will model performance of nuclear warheads and materials to ensure long-term viability, security and safety – this will be supported by a joint Technology Development Centre at Aldermaston in the UK.
Operational Matters
It was decided to sign a Letter of Intent, creating a new framework for exchanges between UK and French Armed Forces on operational matters.
Industry and Armaments
It was decided to direct the UK-France High Level Working Group to strengthen its work on industrial and armament cooperation.
