Humans are aggressive territorial animals which mean there will always be wars.
The world is split between democracies and dictators, with dictators starting most wars due to the oppression of their subjects (civil wars) and to the lack of checks on their leader's power so they start wars with their neighbours and other countries they disagree with.
Well yes, after my time on this earth I have learnt that, and my simple (hopeless) plea for "no more war" was I thought what the vast majority of humans hope for. They do not wish for war.
Throughout history there has either been power hungry and greedy monarchs, emperors, empire building politicians, dictators, or complete arse hole war lords and nutters, always men (I think without exception) who are prepared to see the commoners killed and injured for personal gain. The greed of man is such that, as the great philosopher Thomas Hobbes (1588-1679) recognised and I quote:
" " No arts; no letters; no society; and which is worst of all, continual fear and danger of violent death; and the life of man,
solitary, poor, nasty, brutish, and short.
It is not wisdom but Authority that makes a law.
The condition of man... is a condition of war of everyone against everyone."
Man is simply conditioned to making war, to him peace is purely an interlude, like the sun between showers. Until this condition is cured, by a bloody miracle or the Apocalyptic end predicted by many, then we live with the knowledge of constant war.
In the area of Europe (not the EU!!) we can draw some satisfaction that since we sorted out our previously constant political and imperialistic differences, with democracy in some form or another taking control, we have for 72 years enjoyed peace. No longer do we feel obliged to fight the French, the Spanish, the Dutch or of course the Germans, and neither do they want to fight us, unless it is at a football match!!
If man had the same emotional feelings as women, who care what happens to the innocents and weak outside of their immediate families, who also never want to see their loved ones lives put at risk, then war would never happen. If women ruled the world............................but now(in 2017) I am straying into fantasy; maybe in a thousand years, IF we ever as a species get there, we will learn that and see it in practice.
No, war is a reality, but it is a tremendous waste of human blood, sweat, tears, and commodity.
