The largest trading partner of Germany is the USA. So you can see why they have a massive trade surplus. And that is good for Germany, but not for the USA.
In the long term, this is what is best for the country, because with advances in AI and outsourcing jobs to cheap countries (this isn't just manufacturing, it's also office jobs), people are going to struggle to find good jobs in the USA if this keeps up. People just have to accept some short term pain for some long term gain.
And didn't Trump made an exception for semi-conductors? So those manufacturing jobs that MacRumors are so worried about doesn't even get affected that much.
