Really? The nickname "five eyes" derives from the fact that all the anglophone nations collect intelligence and share it with the others. This alliance allows the anglosphere to collect intelligence, especially signals, from around the globe because of their geographical distribution. Your suggestion would cut the US out of intelligence gathered by the Aussies at Pine Gap, UK signals intelligence from GCHQ, and the Communications Security Establishment Canada.
So because of a dumb UK envoy who has resigned in disgrace you would cut off US access to a trove of signals intelligence. Good idea, good luck with that.
GCHQ was involved in the attempted Coup against citizen Trump, president Elect Trump and probably President Trump.
That caused their director to resign to spend more time with his family.
Canada with Trudeau as their lead anti America cheerleader in Canada is not trustworthy.
New Zealand, give me a break.
Australia’s new PM may be okay. However, an OZ PM years ago, didn’t even know about 5 Eyes. He apparently was such a bad security risk his own Intel people decided to not read him in.
Back to the UK, dealing with them now is like trusting London’s wonderful mayor.
There is no reason why specific, relevent intelligence cannot be shared rather than have everything automatically shared between the members.
