I spoke on the phone with President Rouhani of the Islamic Republic of Iran. The two of us discussed our ongoing efforts to reach an agreement over Iran's nuclear program.

The Russians can't change us or significantly weaken us. They are a smaller country. They are a weaker country. Their economy doesn't produce anything that anybody wants to buy, except oil and gas and arms. They don't innovate. But they can impact us if we lose track of who we are.
