You're being facetious, but the UK and the USA are in some of the tightest relationships of any countries ever. The Anglosphere runs deep with the "Five Eyes".

The UK absolutely and fundamentally should trust the US over China -- after all, the UK and the USA have no-holds-barred sharing of intelligence and spying, while the UK and China have literally no pact at all and are adversarial in that regard.

USA equipment would be orders of magnitude more safe for the British people, as by forming a pact with the US, the US has responsibility to the British government for the intelligence gathered (and vice versa on the mass amounts they collect on us through GCHQ!)

But to pretend that the US is guilty and the UK innocent is absolutely, egregious biased and false. They dragnet over 200 fiber interconnects and literally copy all internet traffic for analysis. They are not our victims, they are our brothers in arms. Don't forget that!
