Russia already captured Crimea and eastern Moldova. They need to capture south Ukraine and part of Romania/Bulgaria.
As I see, Russians already making steps in that direction. For example, they creating fake national groups for smaller ethnic groups, e.g. for my ethnic group (I am Lemko, small Ukrainian subethnic group at west of Ukraine, east of Poland and Slovakia). To control us, they are inventing new language, new alphabet, created "World Congress of Lemko people", and so on, trying to separate us from Ukrainians.
Russia captured eastern Moldova? When did they lose it in the first place? I thought the region was locked between Moldova and Russia since the former declared independence.
Russia has military bases and pro-russian forces in eastern Moldova. Russia has plans to attack south of Ukraine (Odessa) from these bases.
Please tell me difference between that and "captured".
Well, the difference is that the current situation is like "had it, didn't let go, and still control it" but "captured" means "didn't have it, and took it".
