trump wants to bring back the 1920s and make america "great" again. his time frame is before world war one. hence the tariffs and the demonization of canada.

the united states has invaded canada twice, in the revolutonary war and in 1812, and canada participated in the american civil war, on the side of the south. war plan red developed out of that history.

there was also a plan to invade after the last referendum in quebec. clinton had the marines and the airforce on notice.
