If President Vladimir Putin is planning a move against Georgia, where would it come?

That was the question I heard half of Tbilisi discussing earlier this month.

The new Russian legislation allowing regions of another country to seek to join the Russian Federation gives Moscow leverage over a number of regions. First on the list is Transnistria, which has already applied to become part of Russia.

Abkhazia is a more complicated case, as most of the Abkhaz elite emphatically does not want to be part of Russia and still seeks the ever-elusive goal of independence.

Meeting officials from Abkhazia and South Ossetia in Moscow last week, Russian Foreign Minister Sergei Lavrov said that he "respects the will of the Abkhaz people, which has chosen independence."

Lavrov's words seemed to cover South Ossetia by implication too, but the case is very different. It is so small (with a current population of no more than 50,000 people) that its residents are not in control of its own destiny. But, given a choice, many South Ossetians would welcome the chance of union with the much bigger republic of North Ossetia on the other side of the mountains to form a single republic of “Alania” inside Russia.

So we should not discount a report I heard in Georgia earlier this month that the South Ossetian authorities are considering holding a referendum on union with Russia on June 8, to be held in parallel with their parliamentary elections. I was told that this was the message the hyper-active Duma deputy Leonid Slutsky brought to South Ossetia on March 28—although the only press report on the visit recorded Slutsky passing on birthday greetings to South Ossetian leader Leonid Tibilov and presenting him with a copy of Pravda from his birth-date in 1952.

Slutsky was one of the first Russian politicians to stir up Crimea and has also been instigating trouble in the Moldovan region of Gagauzia.

So Slutsky's visit may just have been a trial balloon.

Georgians are nervously worrying about a new wave of Russian pressure tactics against them, designed to halt the planned signing of a European Union Association Agreement in June. But at the moment the only news in Georgian-Russian relations is the continued thaw: the renewal of trade and talk of the restoration of a direct air link.

So one wise Georgian politician told me the government is also bracing itself for another Russian tactic: a charm offensive in which Moscow offers Tbilisi a new deal over South Ossetia in return for Georgia renouncing its European path.

If either of these scenarios come to pass we can be sure of one thing: ordinary South Ossetians will not be consulted about what the Russian leadership intends for them.
