I think in some countries (e.g. Australia, New Zealand) there is a real possibility that COVID may be eradicated within a few weeks/months. That could allow life to mostly go back to normal within the country, provided that severe restrictions are maintained on international travel. Those severe restrictions will do immense damage to industries that depend on international travel such tourism and higher education, and may have to be sustained for a lengthy period (at least a year, possibly several years). That outcome may be much harder to achieve in countries with a larger population and less physical isolation (such as difficult-to-control land borders).
