Its all nuts and eye gouging.
Yup. However, you left out kicks to the shins, groin, and instep which the easiest and most assured. If the scum gets a hold of you...think eye gouge, ear bursting hits, and the always faithful groin kick...although that's never assured unless you place it just right.
Krav Maga teaches you so many other vital areas that would really hurt an attacker and give you the chance to run. Some say, why should I run? Why would anyone other than a SEAL want to continue the fight with an attacker who may more stuff coming at you? Incapcitate the fuck and run. You'll live to live another day.
