The line of 100 years just misses the US occupation of Veracruz and the Zimmerman Telegram (or the Mexican Revolution in general), which was one of the lowest points of US-Mexico relations. US-Canada relations were pretty testy in the pre-WWI era as well, and the declassification of War Plan Red [1] did cause a brief stir.

Then again, the US has antagonized many countries simply by electing Donald Trump.

[1] In the inter-war period, the US military used a series of color classification schemes to sketch out what the US response to wars with various countries would look like. Red was Britain. And in event of war with the UK, the US plan was to invade Canada, irrespective of Canada declaring neutrality (which was Canada's plan in such a scenario).

Which countries has it antagonized? China? Canada and Mexico have signed onto the USMCA. Japan and India's leaders both seem to adore Trump. Watching Trump at the U.N. two weeks ago, he seemed to be a very capable diplomat and seems to have good relations with most nations.

"I'm altering the deal, pray I do not alter it further." But yes, totally okay with USMCA, that's why we decided to put the US first in the name.

Canada and Mexico signed the USMCA not so much because they felt it was better than NAFTA but because they didn't want Trump to do any worse. And it's not like Canada is happy about Trump's emergency steel tariffs that hit Canada's exports--the fact that USMCA would cause Trump to lift them was one of they reasons to sign it, and Trump certainly was in no rush to lift them afterwords.

Not to mention there's lots of dislike towards Trump's tendency to rip up treaties just because Obama signed them--Vietnam wasn't happy about Trump dropping TPP, Europe was not a fan of him leaving the Paris climate treaty or the Iran nuclear treaty, etc.
