Do we agree that it would be a good thing if nobody profited from war?
I'd say that's impossible.
The Inventor of the Maxim Gun and Smokeless Gunpowder was Hiram Maxim which completely changed the technique of modern warfare.
The Maxim automatic gun was the first efficient weapon of its class. Maxim's gun fired eleven shots per second and used the recoil energy of the shot to extract the old cartridge, load a new one, and fire automatically.
Before the first world war, Abdul'baha travelled America to warn on the impending war and spoke to the brother of Hiram on April 15, 1912.
"Hudson Maxim—an arms dealer who had lost a hand while developing explosives—stood in the reception room of the Hotel Ansonia, awaiting a word with ‘Abdu’l-Bahá. He had a bone to pick with the “prophet of peace.”
‘Abdu’l-Bahá greeted him in English: “Welcome! Welcome! Very welcome!” They exchanged pleasantries, then Maxim got down to business.
“I understand you are a messenger of peace to this country,” he began. “What is your opinion of modern war?”
“Everything that prevents war is good,” ‘Abdu’l-Bahá replied.
“Do you consider the next great national war necessary?” Maxim asked.
“Why not try peace for awhile?” ‘Abdu’l-Bahá answered. “If we find war is better, it will not be difficult to fight again; but if we find that peace is the glorification of humanity, the impulse of true civilization, the stimulus to inventive genius and the means of attainment to the good-pleasure of God, we must agree to adhere to it and establish it permanently.”
Maxim tried a different tack: “Fewer are killed in modern engagements than in the battles of ancient times; the range is longer and the action less deadly.”
This was two years prior to the onset of World War I.
‘Abdu’l-Bahá invited Maxim to consider the world beyond the narrow confines of the battlefield, pointing out that “the after-effects [of war] are even more dreadful than the initial shock… The country suffers beyond all power of estimation; agriculture is crippled, abandoned; sustenance fails, poverty and suffering continue long afterward.”
Maxim’s arguments about war that morning ran the gamut of nineteenth-century myth. For example, he claimed that war is human nature; that conflict is an ingredient of healthy social evolution; that economic interests will trump national hostility; that the deadlier the weapon the less likely it will be used—that deterrence equals peace. “War is no more dangerous now than automobiling,” he claimed.
‘Abdu’l-Bahá could present a compelling argument, but He never pressed a point. Instead, He turned the conversation toward the subject of Maxim himself.
“You are a celebrated inventor and scientific expert whose energies and faculties are employed in the production of means for human destruction… Now you have the opportunity of becoming doubly famous. You must practice the science of peace… You must discover the means of peace; invent guns of love which will shake the foundations of humanity.”
“Then,” ‘Abdu’l-Bahá added, “it will be said by the people of the world, this is Mr. Maxim, inventor of the guns of war, discoverer of high explosives, military scientist, who has also discovered and invented means for increasing the life and love of man, who has put an end to the strife of nations and uprooted the tree of war… Then will your life become productive with really great results… God will be pleased with you and from every standpoint of estimation you will be a perfect man.”

I wonder how many can stop selling war?
