The UK is delusional and still thinks of itself as a major power. It doesn't have that kind of influence. And if it thinks that Donald Trump is going to take a stand against Boeing, the US's largest exporter with over 100,000 employees in the US than its delusion is strengtheneing. 
The days when anyone pays attention to MPs standing up in the House of Commons are long over. 
The UK retaliates against Boeing at its own peril. Trump will retaliate and the UK will wind up shooting itself in the foot.
