More than three decades after a car bombing by Hezbollah extremists killed 241 U.S. Marines in Beirut, families of the victims are finally closing in on an unprecedented multibillion-dollar recovery in litigation against the government of Iran over its support of Hezbollah.

On April 20, nearly three years after a federal judge in Manhattan ordered Citibank N.A. to turn over $1.9 billion in frozen Iranian central bank assets, the U.S. Supreme Court finally cleared the way for the assets to be distributed to plaintiffs in Peterson v. Islamic Republic of Iran, as well as hundreds of additional terror victims and their families who hold default judgments against Iran in other lawsuits.
