1) US trying to unsuccessfully hoard supplies, issues with the German testing company
2) China trying to use soft power, but the whole drama feels fake. It is good that they are sending supplies (often faulty and not up to the quality, see dutch story around this) but it doesn't feel genuine.
3) European countries are in-fighting for supplies. Switzerland wants supplies from Germany who is unwilling to supply them. Austria and Germany butt heads.
4) India banning critical medical exports
There are so many stories of how each nation is behaving. Even within the US, states are bidding against each other and the federal government has not shown solid leadership.
When times are grim, humans tend to invoke strong tribal instincts (for e.g. brotherhood that forms between soldiers). If we hypothetically had a more deadly virus than Coronavirus, say with a CFR of 50% and we were unable to stop it, there would be in-fighting between counties and neighborhoods.
There are some good stories too, especially the sacrifice of the healthcare workers, delivery staff and politicians.
When times are great -> Globalism
When times are tough -> Isolation and tribalism
