To be fair, war is actually a lot like gambling, most of the time it is boring sameness run through with a constant low level anxiety and then when something changes it happens abruptly with no warning. The difference is that when the unusual punctuates the boredom and you win in gambling you get money but when the jackpot sounds on the slot machine of war and something unexpected happens it usually means you are about to die.
It isn’t gambling for the rich though, more like the big loud distraction (that happens to kill lots of people) put on to distract everybody else from them robbing us all blind (on both sides of whatever war you can imagine).
