The UK is a Tier 1 partner. The administration seems like it's one Xanax-fueled dream away from saying the UK should be the 52nd state and suspending technical support in the exact same way the US has done to Ukraine.
That's the relationship between the two. The problem is not that these nations weren't Tier 1 partners. The problem is that the current administration cannot be negotiated with in the most damning sense of "these people can't even be trusted to work for their own self-interest."
