From a New York Times story by Isabella Kwai headlined “With His Speeches, Zelensky Gives Each World Power a Tailored Emotional Punch”:

He told U.S. lawmakers that he had a dream, invoking Martin Luther King Jr. to describe Ukraine’s fight against the Russian invasion. He said to the British Parliament that his country would fight until the end, in forests and fields, a vow resonant of Winston Churchill’s exhortations against Nazism. To members of the German Parliament he spoke of a new wall dividing Europe, echoing the Berlin Wall of the Cold War.
