"If anyone thinks that they can kill our citizens and escape unpunished, we will never allow this," Medvedev told World War Two veterans in the Russian city of Kursk. "If anyone tries this again, we will come out with a crushing response."
"We have all the necessary resources, political, economic and military. If anyone had any illusions about this, they have to abandon them."
Note the "our citizens" part of the statement. I'm reading that as a de facto annexation of the two provinces.
