> and all the deaths were for nothing

Deaths and destruction in wars against significantly weaker countries are never for nothing, as certain well-connected people always get filthy rich, regardless of the end result. The ones who make the decisions, they always get their share, whether through the war hardware industry, mercenary business, the reconstruction industry, the resource exploitation industry, or something else. The wider population might end up worse off and poorer, but who has ever asked them about anything when there is so much money to be made by their ''democratic representatives'' if they play along?
