I agree with that, but we have got these WMDs. We can't uninvent them. It's a real problem. It's no surprise that this verse seems really appealing to me: 'He shall judge between the nations and shall decide disputes for many peoples; and they shall beat their swords into plowshares and their spears into pruning hooks. Nation shall not lift up sword (or WMD?) against nation, neither shall they learn war anymore.' Isa 2:4. It may be pie in the sky but it's something we seem to agree to aspire to?
