Very hard situation. At least this force should be triple counted if West want to do anything. But this is one more situation where is violation against other country and it is real question is the situation which really happen there directed from West.
Technically- if in Libya fly professionals from other countries, this would be problem for West. Also- B-2 was shot down over my country in 1999 (no matter that this is refused to confirm...) so there would not be much advantage in stealth capabilities. Also note that crew which fall there would be faced with people rage.
Very bad situation
