“And shame on the Japanese officials for not taking passengers off that ship, especially after it became clear that the virus was being spread between passengers several days ago.”
Yes and no. Japan will ALWAYS put their people first (for example, don’t try having a legal or criminal dispute there if you’re not Japanese, it’s hopeless). We could learn from them...but still, there were probably options, such as offloading them to islands (Japanese or otherwise).
I fully understand that the Japanese had their own citizens protection as the highest priority (just as the US would), but a civilized nation has an obligation to help give the best basic healthcare to even foreigners under their jurisdiction. In my opinion, Japan failed that obligation here in this case.
