I want to know the answer to the following question:
What would possibly prevent the even spread of relief benefits from Iran's nuclear and sanctions deal of 2015?
All the background I'm provided with is that "Following a successful implementation of the 2015 nuclear and sanctions relief deal, the resulting benefits might not be distributed evenly across the Iranian economy as political elites such as the Islamic Revolutionary Guard Corps have garnered more resources and economic interests.". Is that enough to answer the question?
