Iran has by many accounts been on the cusp of a middle class revolution (revolution might be too extreme a word) which threatened an end to theocracy, but international sanctions were definitely holding them back from achieving the sort of economic independence required... if the middle classes really can burgeon then they could become a very popular/influential nation, very quickly... and hopefully you can then see some sort of positive Domino effect radiating out.

Or something shady comes to light in the next year or so and we all go to war again anyway...
