Threats and sanction against Iran prevents new enegy investment, but now Iran gets 10 times more for the same oil comparing 10 years ago. Because that time, owing to economical prosperity of US, iran was getting 8 USD / barrel but now gets 80 USD/barrel, but pays less than twice for sanctioned itmes which at most compose 50 percent of Iranian imports.It means that with the tensions Iran gets at least 8 times more money than 10 years ago when MiddleEsat was calm!!!! Furthermore, with the high oil price, US and European countries have to buy their oil more expensive from every country. So they would be more weak to withstand Iran.
