Will Russia's invasion of Georgia cause more problems between Russia and the US?

Russian troops poured into Georgia Saturday as fighter jets unleashed bombs over the country, ratcheting up fears of open war on Europe's border. Russian airborne troops reached Tskhinvali, the capital of the breakaway Georgian territory of South Ossetia, where fierce fighting was reported. Russian state media reported some 100 military flights were planned to transfer more units to the city.
