with all the doom and gloom projected on this page a mass harakiri for iranians seems inevitable
but i recall seeing this movie before and it ended differently!
I don't have a crystal ball.
Iran's economy depends on all types of factors.
the Region (what happens between Pakistan and India and China).
Iran's own political stability or lack there of.
weather
energy prices.
if the current governing regime in Iran can survive for another 10 years, one can argue the economic outlook might improve at a good clip after that.
presumption: a mega deal has been reached with west, china and ... about iran's role as regional power.
If the government falls apart. you will have chaos for a minimum of 10 years. There will likely be 20 years of instability due to possible efforts to balkanize the country.
If Khamenie dies in say three years then things will probably get much worse for about 2 years till the new establishment can put away their competing factions.
the so called games theories variables start getting out of hand.
One cannot imagine anything very good for next 5 years.
energy prices will be low
relations with west will remain constrained.
