In general, I think of defense spending as insurance more than a jobs program. You have to spend a certain amount (relative to your adversary) in order to be protected.

Different countries have to spend more or less depending on their policy goals. The U.S. wants to maintain a global maritime order, fund NATO, combat Russia, deter China/NK, fight terrorism, and protect allies across the globe. This wishlist requires an expensive military, though existing budget could probably be spent more effectively.

Military spending data across countries is somewhat uncertain and is sometimes willfully misinterpreted by partisans. Michael Kofman argues that adjusting for purchasing power parity China spends almost as much as the U.S.:

Related idea: reduce the number of siloed nuclear missiles while keeping the silos open. This would maintain all the jobs in the small towns that depend on them and spread out the targets of a nuclear attack. Seems like a politically-feasible route to nuclear disarmament.
