They mostly don't.

Or rather, when other countries say "sanctions", they are almost always talking about something completely different than the United States.

This is not about countries sanctioning each other. This is the US sanctioning a local company because a foreign company doesn’t follow certain US laws in foreign soil, where such laws don’t apply.

It’s a bit like the US arresting your mom at home in Texas because you ate a baggie of magic truffles in Amsterdam.
