When someone says he'd like to destroy you, spends half a trillion dollars pursuing that ambition instead of feeding his people, and is in the midst of attempting to wipe one of your closest allies off the face of the earth, I think you should believe him.

Alleged methods of torture include whipping and beating, electric shocks, the extraction of nails and teeth, boiling water pumped into the rectum, heavy weights hung on the testicles, tying the prisoner to a metal table heated to white heat, inserting a broken bottle into the anus, and rape.
Good luck convincing Iranians that they should welcome your kind into their country for any reason ever again.
I am skeptical that your description is an accurate depiction of Iranians' views regarding the US and their own government. It seems more likely that you're ascribing your opinion to a much larger group than is justified.
No one wants my kind (Americans?) in Iran until they can go there as tourists. Apparently around 80% of Iranians would like that to be possible though.
