Ukraine’s Jewish president Volodymyr Zelenskyy brought up the Holocaust to snap back at former Jewish U.S. Secretary of State Henry Kissinger, who argued this week at the World Economic Forum in Davos, Switzerland, that Ukraine should give up its hope to reclaim territory that Russia annexed in 2014 in the interest of stopping the current war as soon as possible.

Henry Kissinger said Monday that Ukraine should end the war by accepting the “status quo ante” — in other words, Russia’s effective 2014 annexation of territories in eastern Ukraine.
