I forgot...yes they are.
Operationally, B2s would still be the better choice. 1 plane vs 4 planes. 2 aircrew vs 8 aircrew. No country clearance required. Stealth, which is essential if you're not going to declare war against Libya and destroy their air defense system. This is exactly the sort of thing B2 squadrons train for.
That seems to make sense to me. I didn't understand the suggestion that the B-2 was chosen for some nefarious reason.
