Since Iran's 1979 Revolution that ended a generation of US-installed fascist tyranny, the US has thrown everything at Iran conceivable short of all-out war. It threw a proxy war against Iran in the 1980s with Iraq. This went on for the better part of the decade - about 8 years. Over the years, over about 41 years, the US has sanctioned Iran many, many times. All US sanctions are illegal.
