Potentially, if a particular German philosopher is to be believed, then war has always been a result of material deficit or for material acquisition - as long as people are disunited and have the capacity for an 'us vs them' mindset while also existing in an economic system that necessitates the acquisition of goods from a third party, then war is inevitable. Provided there was a global political consensus and peace and an economic system that fulfilled all material needs on both a personal and international scale, then war would be pointless and anomalous, likely between rebelling extremists and radicals. However, we are far from such a system, and as such there are multiple intersecting conditions seemingly ever present that perpetuate conflicts globally.
