If it was still Trump and Johnson a deal would have been done where Johnson bent us over to be dry bummed by the States so he could shout about having got a deal. But it was Biden - and Biden hates Johnson with his every fibre because of Johnsons previous racist comments about his mate President Obama's ethnicity. SO as long as it was Johnson there were never going to be any talks.
Then there was Truss - a fleeting skip fire that the Americans must have watched in disbelief and now we have Sunak. Thing is they can see the damage to our economy done by Brexit - how its losses pile up and how we are unable to grow as companies pull out or just decide to locate in the EU rather than the UK. The US administration has more interest in the EU market - its bigger and more vibrant with far more people to sell stuff too.
America can deal with them and just pass us by and like an asset stripper wait until we are in a state and cut us a shitty deal thats all in their favour with a promise that they will keep our heads above water....... just
