Afghans are so dangerous! (5)
I believe the answer is:
hairy
'dangerous' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for hairy that I've seen before include "like Esau" , "fraught with danger" , "An ape may be" , "Like many dogs" , "Perilous" .)
