True, though Russia has the most potential to expand inwardly like the Ottomans and if they can avoid the disasters of the 20th century, or at least lessen it. Then Russia can easily become the second if not first power in Europe.Indeed, the geopolitical game after 1917 will be a fine balancing act between the former members of the Entente.
Though I guess it depends on how things go, France for better or worse needs Russia just in case things go bad with Britain (I suspect Ethiopia might be a flashpoint and who get's Italy's colonies) and most importantly to prevent Germany from having good relations.
Just like for decades Europe needs Russia's resources for their economies and energy, something that will only get worse in the future and this time only Britain has a great supply in the forms of the Trucial states and Kuwait.
