IMO the key issue that caused it to spread so much in the US is there weren't restrictions on mobility. If borders were closed between states, and stricter lockdowns were put in place in hot spots, it could have been controlled.
A lot of smaller European countries are starting to get to the same point as NZ because that's exactly what they did - they restricted travel between borders and required any citizens returning home to self-quarantine. In a lot of places people regularly travel across borders for work, shopping, leisure etc, so Europe as a whole can be compared to the US in this matter. In my country they did this before even the first death, and two months later life is now starting to return to normal.
Along the same lines, it's not surprising that larger countries like Italy, Spain, France and the UK have a worse outbreak, as they put few restrictions on travel domestically and what they did was too late.
