WARSAW — President Biden delivered a forceful denunciation of Vladimir V. Putin’s invasion of Ukraine, declaring “for God’s sake, this man cannot remain in power” and casting the military clash as the “test of all time” in a decades-long battle to defend democracy.
In a speech from a castle that served for centuries as a home for Polish monarchs, Mr. Biden drew a stark line between the forces of liberty and oppression in the world. He described the face-off with Mr. Putin as a moment he has long warned about: a clash of competing global ideologies.
“Russia’s choice of war is an example one of the oldest human impulses — using brute force and disinformation to satisfy a craving for absolute power and control,” he declared before a crowd of hundreds of people. “In this battle, we need to be clear: this battle will not be won in days or months either. We need to steel ourselves for the long fight ahead.”
The president unleashed an angry tirade against Mr. Putin for the claim that his invasion is intended to “de-Nazify” Ukraine. Mr. Biden called that claim “a lie,” noting that President Volodymyr Zelensky is Jewish and his father’s family was killed in the Holocaust.
“It’s just cynical. He knows that. And it’s also obscene,” Mr. Biden said.
Mr. Biden said the war in Ukraine was nothing less than an extension of the Soviet Union’s long history of oppression, dating back to its military invasions of Hungary, Poland and Czechoslovakia in the 1950s and 1960s to end pro-democracy movements, following the end of World War II.
Those countries won their freedom from the Soviet Union, he said, but said that “the battle for democracy did not conclude with the end of the Cold War.”
“Today, Russia has strangled democracy and sought to do so elsewhere,” he said.
The president spoke directly to Russia’s residents: ‘Let me say this if you’re able to listen,” he said. “You the Russian people are not our enemy.” He described the horrors suffered by Ukrainian people during the past month. “These are not the actions of a great nation.”
