The quote I found was the alternate “Cathargo delenda est.”
I had 7 years of latin in high school. “Carthago delenda est” means “Carthago is destroyed”. Cato’s expression has become a saying in educated Europe, and it is referred to by the first two words “ceterum censeo”. With other words, if someone wants to always reiterate a point, it becomes his “ceterum censeo”.
