A Canadian radio host noted,
“It’s like clockwork. The world gets mad at America, and Americans go, ‘Oh no, quick! To the maple leaves!’”
This phenomenon, known as flag-jacking, has persisted for decades. When America's politics face international disapproval, some US travelers attach Canadian flags or stickers to their luggage in hopes of avoiding negative attention abroad by posing as Canadians.
In a 2005 episode of The Simpsons, Lisa Simpson explains the tactic to Bart upon arriving in Italy:
“Well, some people in Europe have the impression that America has made some stupid choices in the past, oh, five years. So, for the next week, I’m from Canada.”
With the Trump White House facing global disapproval, many Americans once again seek out red maple leaf patches and stickers online before traveling internationally.
Summary: Americans often adopt Canadian symbols while traveling abroad to escape negative perceptions tied to U.S. politics, a strategy that has been used since the Vietnam War era and resurged during recent conflicts and political climates.
