It's an easy political win because we've so clearly lost at this point. If they strap Biden to the Golden Throne and roll him out there again for 2024, or if Harris manages to make it to the Iowa caucuses this time, expect them to pound the table hard with this one.
The military-industrial complex will still get plenty of cash from Space Force, Syria, Yemen, and endless drone strikes and special forces operations across the globe. This will inherently be lower-profile, and will get even less press as it's increasingly privatized. Look also for more talk about "we need to re-tool the military for fighting Iran China a peer- or near-peer enemy."
Whatever imperial hesitancy exists in the U.S. government exists almost entirely in the Democratic Party, so you probably have some congresspeople and lanyard dorks who are earnestly pushing for this. Of course, most of them will be easily conned into our next imperial adventure, because we'll totally have a good reason then and it'll totally go differently.
There's an outside chance that they think this will turn down the temperature on some of the rising leftist sentiment in the U.S.
