Do you know what happens to countries that impose unreasonable counter-tariffs? We just increase our tariffs. In fact that is exactly what Trump said he would do and those nations backed down.
Do you actually think the world would be better off without us? Think about that for a minute. Let that sink in. What happens to you without the United States? What happens to freedom without the United States? Do you think your life will be better or worse without the United States? If better then why are you still living here? Move. Go find that utopia you think is out there.
Do you think so little of our country to think the world could do fine without us? Is the world at the pinnacle of technological advancement to where they can no longer advance? So you think we've learned all we need to learn, we've cured every illness, we have invented every tool to benefit mankind?
95% of all of the major life changing advancements in the world today came from the United States.
Why the United States? Because of freedom. The left has killed a lot of freedoms over the years and has put a severe stranglehold on innovation these days, but we are still the freest country in the world. Before Steve Jobs died, he referred to when he started Apple compared to all of the regulations that the government imposed on business towards the end of his life. He said if he had to build Apple before he died, he couldn't do it. There's just too much red tape in the way now.
Regardless we still have some freedom comes innovation, more than any other nation. The free market rewards innovation. Socialism punishes innovation.
Now all of that innovation is being sent, mostly, to China to be built because Chinese slave labor is less expensive than paying Americans to build it. We still innovate but because it is impossible to turn that innovation into an affordable product, we send it to China do be made. Because of that we have made China technologically our equals at the expense of the United States. Had we not done that China would still be 100 years or more behind us.
"isolating ourselves and pissing off pretty much every single other country in the world while doing so does not sound like a good idea for the future."
