The alternative is cooperation. Do you remember the beginning of the pandemic when US states were in a bidding war over PPE and the US federal government was seizing PPE shipments going to Canada? That went away with better inter-state and state-federal cooperation, not more nationalism (or state-ism or whatever). Why should the procedure that works for US states, Canadian provinces, and EU member states (i.e. distributing doses based on population) not work on a larger scale?
