It's as if you were to say, "Oooh I really like this curry, but we next time we need to make it without the spices."
Hitler thought he could rule Europe- but first he had to get rid of all his clever people- many of whom were Jewish, others of whom were gay or otherwise "degenerate".
Stalin had a similar idea.
Chairman Xi may well succeed in shutting down Hong Kong because he's the one with the muscle- but it'll be his own funeral in the long run.
I don't expect the Chinese Communist Party to last for very much longer.
Here in the Commons Mr Johnson has just opened a "bespoke route" for Hong Kong people with a British National overseas passport to come to this country and get on the conveyor belt towards full citizenship. It's the least he can do- and both the decent thing but also very much in our interests. Chairman Xi is moving to get rid of his best brains, his sharpest entrepreneurs- and we'll be very happy to take them off his hands.
China's loss will be Britain's gain.
So thank you, Chairman Xi (you twit!)
