The fat senile hog in the White House is seriously fucked up. The real reason is that there would have been major anti-Trump demonstrations, not anti-American, but anti-Trump.Sounds like diplomacy to me.
Openly admitting that the US UK alliance can't withstand a US president that isn't politically correct, would be a serious and negative milestone.
It is true, but openly admitting it would be problematic.
The UK is fucked up.
I don't recall Americans ever saying that the UK Prime Minister was not welcome.
The Alliance between us was bigger than any one man.
But now, the UK is moving away from US, just because they don't like our President.
That's the issue here. And Trump did the right thing by not stating that publicly.
This behavior by the UK is the problem and a very bad sign for Western Civilization as a whole.
