or maybe you could change your thinking a little and realize that the more a country like Iran depends on exports to the US for its economic health the less likely they would want to damage that relationship.
oops....i forgot you aren't from the US. well the same applies to all 'western' aligned countries.
Unfortunately, it does not work that way. You are applying western style thinking to a middle eastern culture. The best thing we can do is to stop our dependency on oil. Once the west stops buying oil, or it runs out, they will have nothing to export. Nothing to sell and nothing to buy food with. If you think the region is unstable now, just wait until that happens.
