Here is more from the Washington Post:
Former president Donald Trump has privately said he could end Russia’s war in Ukraine by pressuring Ukraine to give up some territory, according to people familiar with the plan. Some foreign policy experts said Trump’s idea would reward Russian President Vladimir Putin and condone the violation of internationally recognized borders by force.
Word of Trump’s plan for Ukraine circulated in Washington last November at a meeting at the Heritage Foundation between right-of-center foreign policy figures and a visiting delegation from the European Council on Foreign Relations. Former Trump White House aide Michael Anton described the expected contours of Trump’s peace plan as Ukraine ceding territory in Crimea and Donbas, limiting NATO expansion and enticing Putin to loosen his growing reliance on China, according to multiple people present for the meeting, who like others spoke on the condition of anonymity to describe a private discussion.
WaPo notes that James Carafano, a Heritage fellow and senior counselor to the think tank's president, convened the meeting. Meanwhile, Jeremy Shapiro, head of the Washington office of the European Council on Foreign Relations (ECFR), brought the group's delegation to the November meeting.
Michael Anton is a Senior Fellow at the Claremont Institute.
