I don't know enough about any of this stuff to have an informed opinion, but I think the insinuation is that it was going to happen anyway because our financial system and economy are so delicate and artificial. But if the whole thing does collapse because of a trade war, there's really only one person I can blame.
Edit: If the stock portion my retirement fund blows up, I will blame myself because I came close to pulling out all my money in January and putting it into a high yield savings (still over 4% at the moment).
