Ahkeelyou's heel 

Achmed's weakness.

It is often quite difficult to get Achmed to cooperate or even hold a decent conversation, but if you offer him a bomb or other device of mass-destruction, that is his Ahkeelyou's heel, and you will totally have him eatin' outta yer hand --- anything that involves widespread annihilation and catastrophic ruination appeals to him immensely.
