Ukraine wants “real peace, not appeasement” with Russia, its foreign minister said on Thursday at the Organization for Security and Cooperation in Europe.

Axar.az informs, citing Reuters, “We still remember the names of those who betrayed future generations in Munich. This should never be repeated again. Principles must be untouchable, and we need real peace, not appeasement,” Ukrainian Foreign Minister Andrii Sybiha said in a speech to the OSCE’s annual Ministerial Council.

He was apparently referring to a 1938 agreement with Nazi Germany in which Britain, France and Italy agreed to Hitler’s annexation of the Sudetenland in what was then Czechoslovakia. The agreement is widely used as shorthand for failing to confront a threatening power. Russia was due to speak later.

“Europe had too many unfair peace deals in the past. All of them only led to new catastrophes,” Sybiha said while thanking the United States for advancing peace efforts and pledging that Ukraine would “use every opportunity to try to end this war.”
