The U.S. ambassador to the United Nations said Friday there should no longer be any doubt that Russia intends to dismantle Ukraine “and dissolve it from the world map entirely.”

Linda Thomas-Greenfield told the U.N. Security Council that the United States is seeing growing signs that Russia is laying the groundwork to attempt to annex all of the eastern Ukrainian regions of Donetsk and Luhansk and the southern Kherson and Zaporizhzhia regions, including by installing “illegitimate proxy officials in Russian-held areas, with the goal of holding sham referenda or decree to join Russia.”

Russia’s Foreign Minister Sergey Lavrov “has even stated that this is Russia’s war aim,” she said.

Lavrov told an Arab summit in Cairo on Sunday that Moscow’s overarching goal in Ukraine is to free its people from its “unacceptable regime.”

Apparently suggesting that Moscow’s war aims extend beyond Ukraine’s industrial Donbas region in the east comprising Donetsk and Luhansk, Lavrov said: “We will certainly help the Ukrainian people to get rid of the regime, which is absolutely anti-people and anti-historical.”

Russia’s deputy U.N. ambassador Dmitry Polyansky told the Security Council on Friday that “The de-Nazification and demilitarization of Ukraine will be carried out in full.”
