Iran is a bad actor, a trouble-maker on the international scene. It keeps wishing the death of the "Great Satan" (that's us) and brags about their efforts to that end. We need to return the favor. If there are anti-government Persians in exile, facilitate their efforts.
Designated offices at our departments of State, Defense, CIA, FBI, etc. should wake up every morning asking themselves if we have done everything short of open warfare to make the leaders of the "theocratic Islamic Republic" and their lackeys look foolish and feel embarrassed, unhappy and miserable. A degree of childishness in these dirty tricks is probably unavoidable, but don't forgo actual malice and spite.
