Could Banning Pornhub Be Canada’s Nuke in the Trade War?

Canada has been a long-time friend and ally of the United States.

The longest non-militarized border on this planet.

And, can you say "NORAD?" I knew you could.

Why is Pres Trump treating Canada as an enemy and Pres Putin as an ally?

Haskell Free Library and Opera House
en.wikipedia.org

... The Haskell Free Library and Opera House (French: Bibliothque et salle d'opra Haskell) is a Victorian building that straddles the Canada"United States border, in Rock Island (now part of Stanstead), Quebec, and Derby Line, Vermont, respectively. The Opera House opened on June 7, 1904, having deliberately been built on the international border. It was declared a heritage building by both countries in the 1970s and 1980s.

The library has two different addresses: 93 Caswell Avenue, Derby Line, Vermont, and 1 rue Church (Church Street), Stanstead, Quebec. ...

Overview

The building was designed by architect James Ball in the Queen Anne Revival style. The first floor houses the book collection and reading rooms and a 500-seat theater occupies the second and third floors.[3]

The library collection and the opera stage are located in Stanstead, but the main entrance and most opera seats are located in Derby Line. Because of this, the Haskell is sometimes called "the only library in the U.S.A. with no books" and "the only opera house in the U.S.A. with no stage". There is no entrance from Canada; however, there is an emergency exit on the Canadian side of the building. All patrons and visitors must use the U.S. entrance to access the building. Patrons from Canada are permitted to enter the United States door without needing to report to customs by using a prescribed route through the sidewalk of rue Church (Church Street), provided that they return to Canada immediately upon leaving the building using the same route.[4]

A thick black line runs beneath the seats of the opera house and diagonally across the center of the library's reading room to mark the Canada"United States border.[5] The stage and half of the seats are in Canada; the remainder of the opera hall is in the US. The building has different postal codes (93 Caswell Avenue, 05830 and 1, rue Church (Church Street), J0B 3E2) and different telephone area codes (+1-802-873-3022 and +1-819-876-2471) in its two respective countries. ...

Why does Pres Trump want to destroy this long-time friendship with Canada?
