Russia has announced that one key measure that will be taken in response to Ukraine's ramped-up drone attacks on Russian territory, including last month's major strikes on the Moscow area, is the significant expansion of the border 'buffer zone' between the waring countries.

"A security buffer zone on the Russian-Ukrainian border is conditioned by the aggressive nature of the Kiev regime and the Russian military is engaged in this process systematically reaching the appropriate progress," presidential spokesman Dmitry Peskov said on Sunday.

In essence this is the Kremlin saying that Russian forces plan to permanently take over territory deeper into Ukraine.

"Based on the aggressive nature of the Kiev regime and in order to insure the safety of our citizens, we are setting up a security zone, or the so-called, buffer zone," Peskov continued. "This buffer zone is being created systematically. We do register significant results regarding the terms of our troops’ advancing."

"There area should be no in no one doubts that it would will be serve to extend the necessary area ensuring our security," he added.

"Our troops are advancing," Peskov continued. "No one here should have any doubt that our military is proceeding systematically, and we are seeing concrete results."

He cited the taking of Konstantinovka: "This is a milestone, it is the most important step towards taking the common fortified area of Kramatorsk and Slavyansk," he claimed according to TASS.

President Putin has of late been taking steps to strongly signal he's committed as ever to completing the war aims of Russia's 'special military operation' - despite reports of nationwide fuel shortages, and also a full-blown gasoline supply crisis in Crimea.

The Kremlin released footage on Friday evening of the 73-year old Russian leader visiting an auxiliary command post to meet with the chief of the General Staff of the Armed Forces.

Putin wore a military uniform, which Russian state sources described as a sign of his resolve to "finish off the terrorist neo-Nazi vermin".

English-language RT's response: "...seems to desire for that security zone to begin on the Polish border."

The scene appeared aimed primarily at the West, which has been questioning Moscow's resolve due to the now frequent Ukrainian drone hits on sensitive energy infrastructure.

President Trump has also lately appeared to pivot back to wanting the resolve the Ukraine conflict, while still seeking permanent offramp regarding to the Iran war crisis.
