"Сила есть, ума не надо" apparently a proverb? Have you heard it before?
It seems to mean something like "Has strength, doesn't need intelligence.." => "He who is strong doesn't need intelligence" (I had to look up "ym")
But the translation given is "Violence is the last refuge of the incompetent."
I have never heard this proverb so it can't be very common. What about the Russian one? Did I understand it right - is it worth knowing?
