Provided you never travel to, though or over the USA, volitionally or by ill luck, nor hold assets there, provided your government doesn't have a cravenly subservient extradition-at-whim treaty, and provided you aren't high profile enough for them to bend rules, then US laws probably don't apply to you.
I feel your frustration and, while it is true that any individual person is exquisitely vulnerable to legal and extra-legal coercion by state power, this still does not mean that the laws of one country apply to the citizens of another country.
That's little solace to the people that do things that are perfectly legal in their own country, only to be arrested because their plane had to make an emergency landing at a US airport.
