The strong multiplicity one theorem and its refinements amount to a local-to-global principle in the theory of automorphic representations of $GL(N)$. I will discuss a Galois-theoretic analogue with a surprisingly elementary proof, along with some related questions about the images of $l$-adic Galois representations.
