The UK and US seem to be the only two nations who have been "convinced" that Russia is about to walk over the border; listening to other European nations they just aren't getting the same conclusions from presumably similar intelligence (you'd assume its coming largely via NATO assets)
If Putin pulls back then clearly something has been agreed between Russia, the US and Ukraine (or rather Ukraine probably pressured into accepting it).
Agree though Boris and Truss have been made to look pretty amateur on the world stage
The only ones looking ridiculous to anyone with more than a brain cell are the Russians.
