Unless there is a clear conflict of interest, such as an "expert" urging a particular course of action which aligns to benefit their employers, then the audience should probably just engage their critical thinking a bit more.
The majority of UK experts will probably have opinions that align with UK ethics/morality/society and urge options that benefit the UK state and it's allies. I would assume that would be an absolute given too.
When I watch Chinese citizens give their expertise on matters, I know that it will probably align with the Chinese state and benefit them (as opposed to strictly the UK state). Have people lost all of their critical thinking skills?
