With number 1 there's the minor issue of it being considered a treason in many countries legislation. That puts it right into the realm of, "don't ask the question, if don't want to hear the answer".

Unfortunately, for number 2 to have an actual effect, one should use the courts to make some examples according to the number 1. I may be completely wrong, but I assume many an EU intelligence officer being more loyal to USA than their own politicians. So some beatings may be required, until morale improves.
