I do not see the tourism industry mentioned here but I have to imagine that is a huge loss right now. Most of the world is not visiting the US right now which means projects and planning that was made in anticipation for summer has probably been halted or heavily reduced.
I recently went back for a funeral, and I had to spend a moment reminding myself that it would be fine for me.
For people who don't have my passport, I wouldn't feel comfortable telling them "it will be fine", though I would still tell a European "the odds of a problem are relatively low." But I couldn't in all honesty say "there's nothing to worry about."
