A day after the deal with Iran over its nuclear program was implemented in January, the Obama administration paid $1.7 billion to Iran to settle an old Iranian claim (unfinished business from the 1970s). At the same time, the Islamic Republic released four Americans it held in prison. The timing was striking: It looked an awful lot like a ransom payment. But the White House denied it. Last week, the Wall Street Journal published further details, which make it all but impossible for any reasonable observer to deny that the White House paid off the regime in Tehran in exchange for the liberty of U.S. citizens: The first installment of $400 million, we now learn, came in cash.According to the Journal report, “Wooden pallets stacked with euros, Swiss francs and other currencies were flown into Iran on an unmarked cargo plane. Foreign currencies were used because transactions with Iran using U.S. dollars are illegal under American law. As Charles Krauthammer remarked, if a company was caught laundering money like this, the CEO would go to jail. Even worse, the massive cash transfer would be especially helpful in funding the clandestine activities of a state sponsor of terrorism. A cargo plane full of currency sounds like the opening scene in a great spy thriller. Except it's not. It's the Obama administration paying off a regime that has been kidnapping and killing Americans for all 37 years of its existence.
