Average bang
That's fine for a small island nation. They might be able to afford a policy of waiting for the world to reach a herd immunity around them.Well obviously the will.keep the monitoring until the disease has reduced sufficiently globally. Of course it may be months even a year. It is absolutely the right thing to do, first responsibility of a country is to ensure safety of its people.
It's not feasible for larger countries.
And let's be honest. Once 70% of the world catches it, the chances are that somebody at point in the future will slip through and bring the disease to them. Then they'll have to go into lockdown again.
