It was actually forced onto the US by a clever US politician who pushed it into the WIPO Copyright Treaty. Europe also approved the treaty and I assume the European counterparts still stand.

The WIPO Copyright Treaty is implemented in United States law by the Digital Millennium Copyright Act (DMCA). By Decision 2000/278/EC of 16 March 2000, the Council of the European Union approved the treaty on behalf of the European Community. European Union Directives which largely cover the subject matter of the treaty are: Directive 91/250/EC, creating copyright protection for software; Directive 96/9/EC on copyright protection for databases; and Directive 2001/29/EC, prohibiting devices for circumventing “technical protection measures”, such as digital rights management (also known as DRM).
