It is a deeply reductionist thing to say about our civilization and culture but, other than a few sociobiologists and maverick nationalists or ethnostatists who admit the biological origin of our social behavior, no one speaks of it. In spite of the many different value systems developed by humans---mostly due to wills to power---human nature has been and remains genetically ethnocentric, even xenophobic, as well as being kin-centered, gender defined, age-graded, heterosexual marriage-making, hierarchical, with group-selection as the primary unit of selection, followed by individual-selection. People instinctively know that the biological origin of our social behavior is true, although it has become politically incorrect to say it, and that taboo, ironically, is itself the result of biological competition consciously or unconsciously hiding real motives.
In the long history of human beings the military and military values were the last refuge, the final resort, which allowed us ultimately to survive and reproduce successfully. Peaceful times come, but the final resort, the last refuge, has always been the willingness of humans to defend their group in armed competitions with other human beings, ultimately for survival and reproductive success. This has not changed in all of history.
But
the West has changed, the West no longer sees that the military and
military values remain the last refuge, the final resort. The recent
fad of defunding local police are an offshoot of this suicidal
behavior. We still need the core military values of loyalty, duty,
respect, selfless service, honor, integrity, and personal
courage---preferably for every man, even nonmilitary men. Movements
like cultural Marxism (demanding equality for the unequal), radical
feminism (demanding biologically unnatural roles for women),
homosexuality (demanding biologically unnatural sexual life styles)
and postmodern relativism (demanding a biologically unnatural
relativity of values), go directly against real human nature and
destroy the military and military values that ultimately save us all.
