There has always been war waged somewhere since humanity has been capable of defining the word "war". There have never been non violent societies, recently or otherwise.
Can you name a country or society or population that has not been involved in a war within the - say - last 100 years?
There was a civilization in South America whose city/cities didn’t have defensive structures, don’t remember the name though.

Warfare does not seem to have been a significant element in Chavín culture. The archaeological evidence shows a lack of basic defensive structures in Chavín centres, and warriors are not depicted in art, in notable contrast to the earlier art at Cerro Sechín. Effective social control may have been exercised by religious pressure, and the ability to exclude dissidents from managed water resources. The climate and terrain of the neighbouring areas outside the managed land were a daunting option for farmers wishing to flee the culture. Evidence of warfare has been found only in contemporaneous sites that were not influenced by Chavín culture, almost as if those other civilizations were defending themselves via warfare from Chavín cultural influence.
Switzerland may have been formally neutral during WW2 but some individuals had other ideas. Was Switzerland neutral through WW1? My 100 years thing goes back to 1924, so post 1914-18.
You could look at Iceland too. It was declared it's own country in 1918, and other than a brief, zero-casualty "occupation" during WW2 has never been involved in a war. It has no military and no legal mechanism to be able to declare war.
Pacifism can only endure as a privileged lifestyle on the backs of warriors. Defenseless, clueless folk get wiped out, enslaved, or subjugated by the first "Viking raid".
How many of the Caribbean states have been involved in wars? (I know Cuba had a civil war that occasionally appeared more external than civil wars reasonably should)
A hundred years isn't a very long time.
That's why I chose it.
That is quite the stretch. There are many countries that live in peace with each other and within for most of the time. Only occasional defensive operations might have been violent, but does it make the society as a whole 'violent'?
Have another roll.
Neutral doesn’t mean non-violent. They weren’t one of the belligerents engaged in WWII but they did defend their neutrality and were a target of actions by the Nazis that didn’t amount to much by the end of the War.
