one of the main differences between U$.$S privacy laws vs E$.$U privacy laws is that E$.$U is protected by General Data Protection Regulation $($GDPR$).$The GDPR aims to protect EU citizens$$ sensitive data and give them better control over how it is accessed and used. while the U$.$S lacks a single governing data protection like the GDPR and uses federal and state laws protect citizens$$ privacy and online data. it would be a challenge because every country doesn't go by the same rules and laws. for an example in the U$.$S we have HIPPA to protect medical information which another country might not follow those guidelines so trying to hold a particular country accountable would be hard
