Debian or Arch or Ubuntu never ask for my confirmation ?

Why don’t you use a distro that doesn’t have such terms?
They all technically are subject to the same terms, they just don’t bug you about it the way suse does
So if I help someone in Sudan, Syria or Iran to install Debian GNU/Linux I can be arrested by means of USA law, right ?
No, not if you’re not American
Possibly, though extremely unlikely. They wouldn’t care unless you were doing it to help set up a nuclear weapons program or something.
This also assumes you’re American, or working from the US. If you’re French and working from France, for example, you’d be subject to French law, not American law.

They can do that, but that’s not the topic of the post.
It seems it’s often unclear whether it does. A user under this post has linked Debian’s wiki page that writes about this, and they don’t have a definitive answer either, just pointers on how to make sure that you are safe
