Zero, you said, "It is not religion that has developed highly destructive weapons for war." I think you stopped too soon with that statement. I think it would have been more accurate to say, "It is not religion that has developed highly destructive weapons for war. It was religion that started the war to begin with."
I fear I must disagree in part with my friend Simon in that I don't think that most wars have been economically based. Some have, to be sure. However, if you examine some of the more recent ones, what you realize is that they are religiously based...almost tribal, in fact.
The late unplesantness in the former Yugoslavia? A war between christians and muslims.
Ireland? Catholics vs. Protestants.
The Levant? Jews vs. Arabs.
Sri Lanka? Hindus vs. Tamil.
Indo-Pak? Hindus vs. Muslim.
Indian Civil? Hindus vs. Sikh.
Africa? Hutus vs. Tutsis
The Russian Revolution? The communist "church" vs. the orthodox church.
The coming American second revolution? the socialist "church" vs. the religion of personal freedom.
Of course this list could go on and on. And in support of Simon, some wars were of an economic nature indeed. The U.S. Civil War was economically based (No, slavery was not the central issue). The Opium Wars between the British Empire and China (perhaps the ultimate immoral war of all time). The U.S. vs. Iraq, Operation Just Cause, and more recently the U.S. vs. Serbia, Operation Just Because.
And there were the wars of imperial expansion like the invasion of eastern Europe by the Mongol Hordes; the invasion of everyone by Rome, and Japan; same with the British Empire - although an argument can be made to include British expansionism as an economically-based war.
And there were wars of unknown, or vague cause: Vietnam, for instance, most likely Johnson's Ego. Or Robert McNamara's.
And finally, wars of distraction: Bill Clinton vs. the aspirin factory.
Anyhowsomever, it seems that religion is implicated in far more than its share of bloodletting. I'm sure you've heard the prayer: Jesus, protect me from your followers.
You seem to be a rare bird on this site, Zero: a person who can disagree without being disagreeable. Who can debate the facts absent falling into the low moral swamp of the ad hominem attack. I hope you persevere.
