Argument: Russia invaded Georgia to reassert its empire
Robert Baer. "The Russian Empire Strikes Back". Time. - "Russia's invasion of Georgia has less to do with South Ossetia than with a Russia that never reconciled itself to losing an empire — or to being treated like a second-rate power all these years. Russia's resentment has only grown as oil prices have risen, turning Russia, with the 5 million bbl. of oil it exports a day, into a first-world economic power. It was only a matter of time, then, before Russia taught the world a lesson."
