In fact it tends not to think of the UK at all, these days.
As to being "fair game": that's true, in the sense that the EU will place the interests of member states over those of the UK. That dynamic must be among the least surprising developments of history, considering it is both obvious and formed the core of every serious prediction in the run-up to Brexit.
