factually.co

... Executive summary-

Global polling shows the sharpest drops in favorable views of the United States since Donald Trump's return concentrated in North America and northern Europe, with Mexico, Sweden, Poland and Canada repeatedly cited as having the largest year-to-year falls in positive sentiment [1][2][3]. Multiple independent surveys -- Pew Research Center, YouGov, Ipsos and national reporting -- converge on a pattern of double digit declines in allied democracies rather than in every region [4][5][6].

1. Mexico and Sweden: the biggest single drops reported

Pew's multicountry survey finds Mexico recorded one of the largest declines, with favorable views of the U.S. falling from 61% in 2024 to 29% in 2025 -- a 32point drop that Pew highlights as among the largest changes across its 24country sample [1]. DW's reporting, relying on the same Pew data, echoes that Mexico and Sweden saw the steepest falls overall, with Sweden down 28 points (from 47% to 19%) between 2024 and 2025 [2].

2. Poland, Canada and other NATO partners: big hits to allied goodwill

Pew and contemporaneous press reporting single out Poland (down roughly 22 points), Canada (down about 20 points) and Sweden as NATO allies where U.S. favorability plunged substantially after Trump's return [3][7][1]. YouGov and the Chicago Council analysis broaden the pattern across Europe, noting roughly eight-point average declines in seven major European democracies and sharper falls -- 20 points in Denmark, 12 in Sweden -- in northern Europe [8][5].

3. Canada stands out in other trackers as well

Ipsos' international tracker records one of the largest single country collapses in perceptions of the U.S., finding Canada's share saying the U.S. would have a positive influence fell from 52% in late 2024 to 19% in spring 2025 -- a 33point fall the firm calls the largest recorded for any country in their series [6]. That mirrored Pew's finding of a large Canadian decline in overall favorability from 54% to 34% year-over-year [1]. ...
