In USA maybe but in European countries the response in every city is pretty much the same for whole country, no?
Charts that compare COVID-19 impact trajectories on a per-country basis (both per capita or not) are not meaningful 1) viruses don't care about country borders, they care about physical social networks (metro areas) 2) response strategies vary from state to state & city to city

Decisions might be made by a central government with the authority to act in every city/region but the response hasn't necessarily been applied in the same manner. 1/2pic.twitter.com/VzWhfi612b

I disagree. Exactly because your point 1, charts could show which countries are taking better strategies. In any case I agree in general but mainly because there is noot a standard (or trustable) data recollectiion.

Unless you plot loglog chart and see that whole europe is following same power law and USA is on the exponential xD

Mitigation tactics are implemented per country e.g. throughout uk. So better to separate uk performance from e.g. Italy, Spain etc. Different quarantine/restriction laws.

It maybe have meaning in the end game when every country closes themselves off. The exponential rate trend of Italy is heading to a good place. Think Easter timeframe they may see the peak (when rate switch from +ve to -ve).pic.twitter.com/Xe6BkfuLxD

Also, if u consider a country as a sum of exponential cases with diff rate, it will be overwhelmingly dominated by the most explosive cluster. Thus, doing rate measurement for a country is near the worst case scenario for that country. But good to err on that side.
