[Halo] How do Earth's national governments operate within the UNSC?

Presumably even after 500 years there are still linguistic barriers as well as some limited national autonomy. Are there French, German, or Chinese planet colonies? How were existing linguistic divides bridged off Earth? Does everyone *really* speak English in space?

The UNSC actually isn't the government of Earth. The UNSC is the United Nations Space Command, or the people in charge of Earth's military in space. The Unified Earth Government (UEG) is the actual governing body over Earth's nations. Think of them as the European Union or the United States under the Articles of Confederation.
