War:

Throughout human history in patriarchal societies, the honoring and revering of wars, battles, and soldiers dying comes with statues, monuments, and buildings scattering the planet in the hundreds of thousands.

Peace:

However, there is only one celebrated International Day of Peace (United Nations), held every year on September 21, but no other days honoring or recognizing peace.

“War comes and goes but a soldier stays eternal”― Tupac Shakur
