Can you explain what's the reason? You can say positive as well as negative reasons.
I think the most common reason for war is the urge to capture resources owned by another jurisdiction. For example, the USA frequently goes to war to secure access to energy resources.
Yes, your'e absolutely right. One of the main reasons why a certain country wage war on another country is because they want their territories,resources and supplies like oil, bank reserves or gold reserves. But, there is also a possibility that this about raising of funds.
Obviously, when you go to war, you'll need every weapons available to fight the enemy and in this case, what's the effective way to requests budget from this? Surely, to request fundings which will come from taxpayers money. I believe they orchestrated their own war because they manufacture their own weapons,guns,ammunition, war ships,tanks and missiles. Im talking about united states here. Yes, i believe they often declare war because literally there's money on it and they gain great profit from it.
