Its also a failure of multilateral organization like UN that is least representative of contemporary reality. Western leaders (expansionist NATO) are complicit too. These are not leaders but herd controllers haggling for power with characteristic ego that see everything disposable, an insatiable urge to acquire, grab and control. These are consolidated outcome of systems that are being nurtured. Its a byproduct of process that segregates and create the other. If you are actively participating in systems that insulates, isolates and dehumanizes then you are equally complicit. War happens when the other is completely dehumanized. Its a breakdown of care. Each death is a wail against systems that doesn't value human life and are least concerned about its impact on life on earth.
