If the US gets hit, everywhere gets hit. It's true, but the further you are from the epicentre the better off you'll be. Europe doesn't have AI companies anywhere near the scale of the US, and they've been trying to divest themselves from American big tech because of Trump.
Investing in Asian stocks would probably be even better in some ways, but the RAM and flash price collapse that's probably coming off the back of the US AI pop will hit them hard.
