The B-2 probably serves more as a deterrent. It tells would be enemy states that if we wanted to, we could bomb them anywhere. They can’t defend against it.
An enemy might think that they have a chance at defending themselves from B-52s, or at the very least, prepare. With a B-2, they could be anywhere at anytime, and no one would even know.
Looks like they live in a dumpster 💅
