This just proves that U.S. has the intention of harming ordinary Iranians.
As I said in other topics, these nuclear negotiations are waste of time. West expects too much, and don't want to give anything in return!
Actually Iran's economy is adopting to sanctions quite well, we may even have to thank the West, because Iran was and still is too dependent on oil revenues, this must change!
We actually live more comfortably than majority of people in Western countries, because price of basic products and services are almost 10 times cheaper compared to high-income countries and we don't have to pay for books, software, etc... because we could download the pirated versions without having to face penalty. It is actually encouraged.
Many Iranian software companies and publishers are making tons of money because there is no copyright law for foreign products in our country, all this could be a very good response to sanctions, considering Iran's market and population.
