What if Canada has been purposely manipulating Americans to focus on the southern border?

-Canada using the entertainment and media industries to portray them as the overly-friendly America-lite people. This lowers everyone’s defenses.
-Using media they convince the United States to hyper focus on the southern border. This brings American defenses to the southern border.
-A “Canadian vs American” trend starts. They use things like hockey games and news focusing on things like tariffs and reasons for there to be malice between the countries.
-Convince the world that fire arms were banned in Canada, when in reality many people are arming themselves. Again, making Canada seem weak.
-Manipulate US allies causing strained relations between them, so they are less likely to come help.
-With the military on the southern border, boom! Canada attacks!
