Iran and oil

Iran is called the number one backer of terrorism around the world and so the US has placed stringent sanctions on Iran and they are working. Iran's main source of export income is oil and they have been shipping 800,000 barrels per day to China. This is down from 3 million barrels per day before the sanctions. The US is now negotiating with Iran and a deal is on the table to remove the sanctions and start buying oil from Iran. If this happens many expect Iran to use the new income to further finance groups like Hezbollah. Others propose that the US increase oil production.
