"War is a racket. It always has been. It is possibly the oldest, easily the most profitable, surely the most vicious . . . It is conducted for the benefit of the very few, at the expense of the very many. Out of war a few people make huge fortunes."
Those words are as true now as when first spoken 90 years go. Whether it's an officially declared war or some euphemism devised to avoid calling a spade a spade (e.g., police action, military intervention, counter insurgency, surgical strike, regime change, peacekeeping operation), it's all a racket and there are strong incentives amongst the powers that be to keep that racket going.
