SAKOKU, a new vocable from japanese ?

Where shall we be in one year? Still covid and no vaccine is a probable scenario.

“THE SPARED”, countries that were able to do the sacrifice of many social habits and protect the population, will be having a low covid diffusion rate and a high conscious level of self-accomplishment. They will face “THE IMMUNIZED”, countries that had a large spread of the pandemic, killing many, and might consider, as having paid the price of a relative herd immunity, to be entitled to economical growth and travel freedom.

How will frontiers will open in this caricatural world?

How will this affect the political relations and military balance for example of Japan and the US? More ever what would mean an isolation environment for a country in the 21st-century?

Would SAKOKU (lock up of the country, isolationist foreign policy) become a new international vocable together with Kaizen, Kaiju, Emoji, Mottainai or Karaoke? Successful Japan's 200 years long SAKOKU ended because the physical threat from outside was no longer matched by internal strength. Covid might lead us toward a long forgotten military escalation unless we find a “new normal” definition and application of SAKOKU.
