The USA has already specifically ruled out any trade deal with the UK if the UK breaks the Irish border deal.
What utter nonsense. The US has not said this.
Nancy Pelosi, the Speaker of the House of Representatives said this is what she would do. However she is not in power and has no ability to bring it about. It is just hot air.
The pity is, some fools believe it is fact as that is the way the BBC reported it.
It's an aspiration from someone with no power to bring it about.
