I suppose we should be so frightened about Chinese 5G that we adopt American 5G instead - TBH I suspect the Chinese will have a lot harder job making anything useful out of my comms than the USA or GCHQ
Warren Peace's point is fatally flawed - even if we had everyone in the current UK Armed Forces redeployed against the "terrorist threat" it wouldn't stop things like the latest London Bridge shooting. It lasted 5 minutes - 300 seconds - and started inside a "private" building. Unless you have everyone in the UK guarded close up 24/7 by an armed guard (and the records show that they have to be guarded in case they go crazy and then the guards guards mighty go...) I can't see how you can do any better than they did last week.
