Yeah, I'd admit China obviously has a shit ton of tarriffs on foreign goods, they're an isolationist shit stack. But that's not tariffs on American goods, they're tariffs on foreign goods. Trump's not pulling a reactionary tariff on China here, he's pulling a tariff on all foreign goods, so the idea that it's America doing the same to China as China's doing to them is ridiculous.
You don't really have anything on the EU, though, you just seem to have given me a directionary that I could use to search product codes, such as, and this is one of them: "Raw hides and skins (other than furskins) and leather: Raw hides and skins of bovine (including buffalo) or equine animals (fresh, or salted, dried, limed, pickled or otherwise preserved, but not tanned, parchment-dressed or further prepared), whether or not dehaired or split: Whole hides and skins, unsplit, of a weight per skin not exceeding 8 kg when simply dried, 10 kg when dry-salted, or 16 kg when fresh, wet-salted or otherwise preserved: fresh."
So, not really examples, more a massive opportunity to waste time. Anyhow, never mind, you're unhelpful and useless. In regards to the overall point, the EU doesn't impose massive tariffs on America and not expect it to react. That doesn't happen. The tariffs are a new move by Trump in regard to his protectionist policies, not a reactionary one. So it's in no way helpful to the US' ability to negotiate over deals.
In regards to this strengthening the economy as a whole, I highly doubt it will. A Trade War will actually mean that they'll actually be a huge decrease in demand for American goods as a whole as as countries raise tariffs, demand is decreased a lot faster than the American demand for the foreign goods tariffs are placed on would rise, as America's losing out on the international community as a marketplace. The businesses being damaged are the more successful businesses than should be staying open, while the ones being helped are the worse businesses that should be going out.
Economist David Ricardo worked on this, with the law of comparative advantage. Basically, it means that with free trade, due to economies of scale arising countries should move towards the production of the goods they have an advantage in as long as free trade exists, because that's how the international community as a whole benefits as well as the individual countries. The reason the aluminuim and steel production are low in America is because America's rapidly moving towards a tertiary economy, because of rising education rates and the fact that it's far better to be a tertiary economy than a primary one. The idea that America should attempt to protect these industries is laughable, because it doesn't benefit the country, or indeed the world as a whole. Instead, America should clearly be looking at expanding the areas where its economy excels rather than protecting dying industries that were only created when foreign trade wasn't able to fill in these niches.
