As part of a week of special coverage on Iran, the BBC World Service has spoken to a number of Iranians about the situation in their country and their fears of possible conflict over Iran's nuclear ambitions.
Amir: "We don't want to change our government. It took years for Iran to have some stability after the 1979 revolution"
My name is Amir. I am 60 years old and own a small business in Tehran, selling building materials.
Business is not going well but I don't mind because at least we have security in Iran and that is very important to me. Look at what's going in Iraq and Afghanistan.
I am not an educated person but I am very interested in international news, so I listen to the Persian Service of the BBC World Service, to see what is going on in the world.
I don't understand why the West is pressuring Iran over its nuclear plans. I heard about an article written by a prominent American journalist that President Bush's plan is to change the regime in Iran.
But President Bush is wrong. Does he want to turn Iran to another Iraq?
We don't want another war. We have already seen one.
We don't want to change our government. It took years for Iran to have some stability after the 1979 revolution.
Another change will require many more years of adjustment and we don't want that.
President Bush doesn't understand about the consequences of such change. Iranians will suffer, not him.
Those who seek conflict are wrong. What would President Bush gain from a regime change in Iran?
He shouldn't just think about his own political plans and what he thinks is right for Iran.
President Bush and his advisers were not in Iran during the seven-year war with Iraq to see what happened and how we suffered and still do because of what it did to our country.
They did not witness what we witnessed. President Bush needs to know that no-one in Iran wants another war.
