The US government does not allow us to sell products in Iran.
This is simply what he replied me in order to my inquiry for an oil industry device. I don't know exactly when the funny war will be over among Iran and the rest of "civilized" world. I don't think we are not to blame, but actually it's not just since the current events on Iran's nuclear programs started, the American government put us under sanctions.
Economical sanctions will affect the Iranian people directly. With the price of 75 USD or higher for each barrel, the poor guys will go poorer.
