Iran is second only to Egypt in population for the region, 79 million to 88 million, almost exactly the same size as Turkey,and more than twice the size of Iraq, Syria or Saudi Arabia, with Saudi numbers probably including all the 'guest workers' and ex-pats. It is, overall, likely better educated than Iraq, Syria or Egypt. So they should just keep on keeping on and negotiate longer term deals with such partners as they can find. They could also profitably invest in their refinery and plastics industries, any higher value products with crude oil as the input. That could provide Iran synergy in its relationship with China. Central Asia is the nearest, biggest opportunity for future development and investment. Iran could supply the educated workforce needed in the Islamic parts of Central Asia for many infrastructure projects as well.

"It is not necessary to have hope in order to persevere."

This says a lot about international trade.
