> Cowardly

How do you figure this? Is the US approach courageous?

> NZ had extreme advantages: an island nation with easy to control borders, a large lead time to prepare, a low population density

NZ discovered cases just days after the US. The US is also not heavily populated. It depends on the source but NZ is about 15 people per km/2 and the US is about 36 per km/2.

A comparison could be made between Hawaii and NZ, and the contrast in how things have gone is quite something.
