Brexit is all about the UK becoming a rival to the EU, not a partner
It shows how limited your understanding really is. Brexit was not about becoming anyone's rivals! It was independence, accountability and choosing our own future, rather than having all the decisions made for us by faceless suits in Brussels, or VDL!
We are happy to be friendly trading allies with the EU, and no aspirations to be anything else.
Trump was not a fan of Nato because Germany and others would not pay their dues, and given they are/were the main beneficiaries to peace and security on the continent, he rightly became fed up! I am no Trump fan but I can see why the Americans are fed up with paying bills for other countries, post world wars.
