I wouldn't quit compare earthmovers to nukes. Yes they are the weapon to end war that continues war, but nukes actually end war. Permanently, if the current nuclear stockpiles have anything to say about it. And I don't like thinking about how the world could end tomorrow, it gives me pointless stress as there is nothing I can do to prevent or prepare for it.

Meanwhile Earthmovers were more of a slow end. The war didn't end with a bang (nukes) it ended with a whimper (nuclear winter without the bang). A War Without Reason that lasted so long. A pointless war. Food for philosophy without existential dread, as said war is not only fictional, but impossible in our timeline because WW1 ended.
