Just like in 2017, Trudeau and Trump agreed to support the expeditious completion of the Gordie Howe International Bridge. Trump 1.0 even listed it as a priority infrastructure project. But Trump 2.0 has held up the opening of the bridge for months based on profound misunderstandings of how the project was funded and completed. And of course the influence of the Moroun family.

The repeated capriciousness of this U.S. administration is undoing any sense of trust and cooperation. Everything to Trump is an all-or-nothing battle to be won. In 80 years on this earth, the man has not learned that mutual benefit is a thing.
