Singapore MFA current advisory for ALL Singaporeans is to avoid travel to Iran due to its volatile situation there....
It is a advisory in the best interest of ALL citizens, but each has free will. Even your 1st post that you saw fit to post here, a Mr Eshan, laid a disclaimer that he would only visit the country when it had achieved peace and is more stable.
Should you feel COMPELLED to go there, then do so, BUT do not attempt to mislead or influence innocent others to do so, with your constant FAILED perceptions that current day Iran is a paradise on Earth. Nothing is further from the truth. The Persians and Iranian citizens had been left long ago behind by their demented TERRORIST TWISTED ISLAMIC leaders and military whom had long destroyed and deprived their citizens of better lives to feed themselves and their loved ones, for decades.
Should you go on a tour, it will probably be North Korean style - hiding realities of poverty and hardships, but showing only facades of beauty and strength,
Should you managed on the visa given, circumvent the NUMEROUS TWISTED ISLAMIC republic of Iran agents and its TERRORIST IRGC brutish soldiers in plainclothes, you will only see destruction and despair, wrought upon by those same beasts upon a beautiful country......should you not be found out and shot dead first.
The insignificant nobody me wish you all the best, and hope to see you on the OTHER side one day or time - a side which is not on this Earthly plane, as no mortal lives forever, and for sure not me, which we all Humankind will eventually return to......
