Sanctions also affect population and create indirect deaths and suffering in the civilian population.
I guess that, just like Madeleine Albright, you believe that 500k Iraqi children death caused by US sanctions were "worth it"? (US still wanted to invade after, proof that sanctions worked!)

Quite a loaded question (a-tier).
Counter-question/game:
Hypothetically, imagine that you become president of US today, inheriting current situation. What would you do regarding Iran situation?
What is the correct action now in current situation?
Spoiler: I think there is no “correct” solution, somebody will be hurt in the end despite best wishes.
Note: Lower supply of oil and fertiliser affects poorer countries more than the rich ones (possibility of famine in Africa). Current Iran government just killed their own civilians a month ago in thousands to end protests; and repressions will likely repeat as protests are likely to repeat. (Irans populace seem to be quite educated and want some reforms) Ground invasion of Iran would cost a lot of lives - civilian casualties always exist.
But honestly, what would you choose to do?
