PLA of China at our front door? in My Therapy Book

“Justin Trudeau invited China’s People’s Liberation Army to train troops in Canada” - It would seem that China is staging an invasion with the assistance of our “friends” to the north. If I have to listen to my mother in law one more time about Canada allowing troops into the country to train right after President Trump is voted out of office I may scream. Why is it that people can take a moment to read a headline but not an extra two minutes to read what is really going on?
