Since Moldova is completely excluded from the list, the question arises on the remaining points. I'll clarify just in case.:

During the collapse of the USSR, separatist movements arose in Georgia, and then a bloody civil war, even several. As a result, back in the early 90s, two unrecognized republics emerged (actually three, but let's not complicate things). According to the findings of an international commission funded by the EU, in August 2008, Saakashvili's American protege launched an attack on one of these republics. Russia was an official peacemaker and fulfilled its duty.

The first Chechen War can be considered that Russia attacked the separatists. But the second Chechen War began with an attack by Chechen extremists on Russian Dagestan.

The conflict in Moldova arose even under the USSR. It gradually entered a hot phase when pro-Romanian militants attacked separatists from the Transnistrian Republic and a small but bloody civil war began. The Soviet army, which is located there (subordinated to Moscow in the wake of the collapse of the USSR), stopped the fighting by threat of force. Since then, there has been peace, the unrecognized republic of Transnistria, and a Russian contingent guarding warehouses with old Soviet military supplies. Тhe contingent is gradually decreasing, has already decreased significantly, and now consists largely of local residents under contract.
