If it gets into stupid piss fights that lead to nowhere and one service won't cooperate with the needs of the other, I think the whole point of separating them is lost.
If the Air Force doesn't want to support the Army, which happens to be the most important mission currently, then just put their butts under the Army just like old times. You'll have wastes of money like the F-22 scrapped in no time.
You can have a generic Military with services reduced to simply the largest divider in the MOS categories.
All will wear the same uniforms.
If they don't get their crap together, might as well do this. Hell I'd hate it too but I'd rather see the job get done.
