Who would blame them, for real? Countries probably should not be faulted for looking out for their own citizens, at least initially.It's Canada and Latin America that are being threatened by the US. It means that shipments from China should now go directly to a Canadian port first to ensure that products designated for Canada arrive in Canada. Maybe Canada will steal all the shipments intended for the US too.
Humanitarianism is certainly important as well and I hope will prevail. But this seems to be the same kind of competition going on among the 50 states as well..due to good old fashioned capitalism, price gouging, and greed. JMO
