I'm not sure german successses are anything to do with action on the part of the government. I've been consistently surprised by the abrupt reversals in policy - with border controls or school closures going from 'out of the question' to 'tomorrow' with very little time elapsed.

I think much of Europe is a little bit like this. Germany will probably be relatively well off because German culture is fairly anti-social, Germans are typically very healthy, and the healthcare system is somewhat robust.

However, I haven't seen any sign whatsoever of a consistent or coherent response to the coronavirus. I expect whatever response eventually percolates out will be fairly rational, since german civil servants are well-paid and competent, but so far, it's been all over the place.
