Does a war have a single cause?

How is something the result of more than one reason?

Lets say a politician wants to fight a war for the very selfish purpose that it will make him more powerful while in office and more likely for him and his party to win an election.

He talks to the bankers, and the bankers love the idea. Bankers always love wars because bankers always get rich over wars. Banking fortunes have been made by loaning lots of money to governments fighting wars. So the bankers think a war is a great idea and agree to use their influence on Congress, the media and society in general to make it happen.

Do you think the politician is going to argue with the bankers about what’s the most important reason for the war and whether its about his career or their profits? No, he’s going to say great to have you on the team and move on.

Then the politician goes to the arms makers. They think a war is a great idea. They get to sell lots of weapons and ammo to the military. And through some back channels they might even sell more to the enemy. So the arms makers agree to the war, and agree to use their influence over Congress, the media and society in general to make it happen.

Do you think the politician is going to argue with the arms makers about the reason for the war? About whether its more important to his career or their profits? No, he’s going to say welcome to the team and move on.

Then the politician talks to the lobby groups that support Israel. They think the war is a great idea. It means one of the regional powers they have to worry about is about to be destroyed by the world superpower. So they agree to the war and agree to use their influence on Congress, the media and society at large to make it happen.

Do you think that the politician is going to argue with them? Argue that the war is more important to my career? No, he is going to say welcome to the team and move on.

The politician then goes to those who want more of a police state. They think the war is a great idea. It means they can crack down on unruly elements who threaten their profits and power. So, they agree to the war and to help use their influence to make it happen.

Do you think the politician is going to argue with them and tell them they support the war for the wrong reason?

The politician then moves on to religious elements. They call Israel the holy land and think a war is the start of Armageddon and their rise to heaven. So they agree to the war and to use their influence to make it happen.

Lets say all of that creates enough influence in the society for the war to occur. Now tell me the single cause of the war.
