OH NO

This was just reported on CBC in regards to the Russia-Georgia conflict: "The US is a strong ally of Georgia and US President George Bush issued a statement today pledging support for what he called Georgia's 'territorial integrity'. The US is calling for both sides to agree to a ceasefire and is sending an 'envoy' to the region." Anyone know what exactly the 'envoy' includes? And what happens if Russia doesn't agree to a ceasefire? And will this be seen by Russian's as the US preventing Russia from protecting the people of South Ossetia? Worrisome stuff.
