United Kingdom. Source of much of the world’s rottenness and still seeks to control the US.
If May is indeed stepping down, one of the reasons will be the unholy shitstorm that’s already been raging in US-UK relations, and is about to go public in a big way. POTUS’ State Visit to the UK earlier this year was a very rum affair. Very unusual: very subdued. UK state behaved like a schoolboy sulking after a sound thrashing: little more than going through the motions, and significant persons were notably absent from all proceedings.
I think it likely to be the UK. “Shocking” because of “Muh Special Relationship”.
