One of my characters has been a hero for his side in a war between nations, when suddenly he has a change of heart and realizes that neither side is right. He is in possession of some valuable assets (people with special knowledge) which he now believes must not be captured by either side. All of the foreshadowing in the story is pointing towards his having to kill these innocent people to keep a bigger catastrophe from happening.
All of this is set in a near future, where all of the major eCommerce providers have merged into a single entity called Consolidated Product Delivery and expanded to serve all people, everywhere. CPD has quietly become the dominant superpower on the planet. The separate nations still continue to claim independence, but each of their economies is totally dependent on CPD.
I'm planning to lace CPD's omnipotence into the story at many points along the telling. The hero will notice that an enemy's weapon has a CPD barcode on it, similar to his own. Later, he will learn that the ammo and gun-sights for his weapon are interchangeable with that of his enemy. During an unexpected urban firefight, both sides avoid shooting at the CPD delivery truck because they think the supplies inside are for them. I will try to be subtle, but I want the final solution (the hero defecting from his side to join CPD) to be believable despite its being unexpected.
So here is the question? Is it believable that an economic entity with no standing army and no sovereign nation status, actually be dominant over all nations, even during wartime? Are there any historical precedence such as the Catholic Church or the Red Cross? And if so, is there any precedence of such an entity granting sanctuary to a traitor during times of war?
