“The nuclear accord reached today doesn’t mean companies can immediately market and sell their products in Iran — the country must meet certain requirements before sanctions will be lifted, and it’s not clear when that would happen — but it does mean businesses are suddenly very close to operating in the country, something they’ve been interested in for some time. Iran is a country of more than 77 million people, and as the Journal points out, today’s nuclear deal would eventually unfreeze more than $100 billion in Iranian cash held in foreign banks, which would give more buying power to the country and certainly could entice companies hoping to bring their products to Iran.”
