Tom Nichols, The Atlantic:
Even by the standards of Trump’s many fixations, his obsession with Canada has become not only weird but truly destructive. He has opened a giant political and economic rift with one of America’s biggest trading partners, a sister nation, and an ally in the common defence of North America and Europe. Why does Trump hate Canada so much?
We can only speculate about what goes on in the president’s head, but his actions suggest a pattern. When Trump is frustrated about something he can’t control, he lashes out at friends harder than he does enemies.
