Shake your head, insult even.
So I shall repeat- the relationship of the UK, as part of NATO, with united European Countries, as part of NATO, has changed due to Brexit. The UK has so far refused to discuss the future relationship with other European countries, as part of NATO
''British opposition to formalising cooperation could be explained by the perception that the EU institutional frameworks for external security cooperation offer 'few incentives for the UK', compared to other, more flexible formats (ad hoc coalitions). The EU's proposals for possible foreign and security policy cooperation with the UK include several areas such as coordination in multilateral organisations, sanctions, crisis management, capability development, intelligence, and development. To this end, the Deputy Secretary General of the European External Action Service (EEAS), Charles Fries, argued before the European Parliament's Subcommittee on Security and Defence (SEDE) in May 2021 that, 'there is huge potential todevelop a relationship with the UK, once London is ready to engage in a discussionon security and defence with us.'' (Official EU document on Brexit implications to European security).
This has not happened yet, and so said relationship is unclear at the moment.
