When I saw the Chinese reaction to the tariffs, I imagined them saying: "Oh, awesome, they're going to shoot themselves in the foot. They'll have trade wars with everyone, and we'll be the ones winning - again."
Very curious on how this all turns out in the end, though. There might be surprises. As you mention, the tariffs only work if everyone believes that the USA is the most important market - as soon as they figure out ways around them, it'll be fine. And the USA doesn't have a monopoly on quality products.
On top - maybe it's even better not to have access to an extreme-consumerism-market - at least for the planet it might be beneficial.
