Weapons and guns and missiles are not just here for sure they Will be used.
But even If Will be small % of them used then it's danger all ready.
I mean look how many missiles are in the world and guns and other weapons the weapon sellers did not invest money in for nothing to build weapons and military equipment off course they want to sell and use atleast few weapons but even If only small % will be used the damage will be done huge.
Even If 1% will be used of USA china russia or UK eu weapons then it's huge damage allready.
And where will be the weapon sellers Will locate themselfes If their own weapons Will be used ? Interesting
It took me some time to understand some things you are explaining but it's all good, nice topic.
I agree that the reason why weapons and missiles are made is to be used. Like you said it is not for show but for war. The producers of these arms both government and private firms are business ventures that want to make a profit. The cost of disposing of expired weapons and equipment is expensive, so these producers will also seek where to dispose of these obsolete weapons. Some developed nations still want to expand their influence in the community of nations. For these reasons, war will never end.
War doesn't have any advantage because it brings only sorrow, destruction, and death. Sometimes I imagine how will Gaza and Ukraine be rebuilt. I am not considering the physical structures but the people. Many children have become Orphans and many of them will suffer from psychological, financial, and educational needs. It will also affect the health of people because of the effects of some chemical weapons or other unhealthy gases produced by other weapons. Many people will die and survivors will go through post-war trauma, it is never a good experience. The war in Ukraine and Gaza is a clear picture of the effect of war which is why we should all promote peace instead of war.
