Does this fall under Godwin's Law or Quirk's Exception?

Lieberman compares terrorists to Nazis.

"I'm worried that too many people, both in politics and out, don't
appreciate the seriousness of the threat to American security and the evil of
the enemy that faces us -- more evil or as evil as Nazism and probably more
dangerous that the Soviet Communists we fought during the long Cold War,"
Lieberman said.

If it's under Godwin's Law, we see in this Wikipedia excerpt that Joe automatically loses.

There is a tradition in many newsgroups and other Internet discussion
forums that once such a comparison is made, the thread is finished and
whoever mentioned the Nazis has automatically "lost" whatever debate was in progress.
