"Violence is never the answer" is a phrase I have often heard by those who will unironically brand Hitler as the most evil man to ever live and consider Abraham Lincoln the greatest President ever to live.
We can debate the merits (or lack thereof) of these assertions, but I don't think these same people see any issue with US going full out against the Axis countries or think Abraham Lincoln was anything but a saint.
Violence was the answer during these times. It was just a matter of who won.
That is not violence it is a defensive use of force against someone who aggressively initiated violence
