If the Kremlin follows through with its purported plans to annex large swaths of southern and eastern Ukraine, as the White House expects, it could fundamentally shift the stakes of the war and make a negotiated settlement all but impossible.
Why it matters: Kyiv and its western backers hope an influx of NATO-caliber weaponry will allow Ukraine to reverse Russia’s gains. But if Russia follows the “playbook” the White House laid out this week, Moscow will claim that fighting is now taking place on Russian soil.
