In Savannah, Georgia, there stand historic cannon with an inscription in French (translated here): The final argument of kings.

“…and I am therefore justified in demanding the surrender of the city of Savannah, and its dependent forts, and shall wait a reasonable time for your answer, before opening with heavy ordnance.

“Should you entertain the proposition, I am prepared to grant liberal terms to the inhabitants and garrison; but should I be forced to resort to assault, or the slower and surer process of starvation, I shall then feel justified in resorting to the harshest measures, and shall make little effort to restrain my army—burning to avenge the national wrong which they attach to Savannah…”

- W. Tecumseh Sherman’s ultimatum to the garrison of this city, December 1864

Sherman’s March to the Sea was an apotheosis of political violence. It deliberately targeted non-military infrastructure.

How long would American slavery have persisted without the march (the war to which it belongs)?

How could non-violence have triumphed in the same crusade?

And the Virginia flag has a graphically depicted murder with an inscription in Latin (translated here): Thus always to tyrants.
