No other western country has actually been willing to do what NZ or Australia did - strict contact tracing, strict lockdowns, and a near-complete ban on entering the country, with those that do being picked up the police or military at their plane and driven to quarantine hotels where the doors lock from the outside.

I don't know why everyone keeps going on about other countries not getting the same results - no other rich country has even talked about trying, as far as I know.
