I fully agree with you salar...for some one who regularly traveled between Shiraz and Tehran with my private auto (once every two months) in 1978,1979..I can tell you this..Shiraz to Isfahan two way road in good condition...Isfahan to Qom...may be 20 km of divided highway the rest two way...I could see the qom Tehran freeway being built but by the revolution still not open....Tehran Karaj was fully done toll divided highway...Karaj- qazveen...partially done.
Inside Tehran no more that 50 km divided and one overpass built by Europeans !!!! And the decking was metal with special coating and Iran had problem recoating that!!!...
What I see now in Tehran alone my head spins..so they sure did a good job with the roads..
Those of us who are old enough to have seen with our own eyes in what state Iran used to be prior to the Revolution, the contrast between the cultivated image and what lied beneath, can grasp the extent of the progress made - under sanctions, under threats, under constant demonization and destabilization attempts by the world's biggest powers. You just summarized it perfectly in a few sentences. And what you described, was the case of practically every sector in Iran.
Younger generations may be susceptible to the programs of foreign-sponsored Persian-language media and the elderly monarchists who appear in them, who of course will not deliver an objective presentation of things. The opposite side has not been so active in balancing out this biased storytelling, and/or has not been featured by these media.
