In this case I would disagree. Look small countries make it much better, easier, smarter. You are right, for make country as regions, but you have to introduce set of rules and regulations between regions.
We did not do it. So we are a big country with greater impact.
No small countries are able to lock down fast and hard and fight it short term, long term unless they close borders for years, they'll get back, too costly to keep fighting, just got to accept like Sweden sooner or later.
Remember, I'm a lock the old and poorly away and the staff that support the care homes, everyone else have an mass orgy and get this thing over it.
