I see, I thought you have your own assessments of how Iran looks and how they conduct their social affairs that you have to label them as Islamic Radical. I found in your response that it depends upon your point of reference and sadly your reference does not justify your allegations in the sense that you got your information from the views of the adherents of Zionism who are now leading the government of Israel who considered Iran as their mortal enemy.
If Iran is like what you accused as Islamic Radical, how come they were able to get the trust of NAM(Non-Align Movement) member countries and even to the extent of giving Iran the NAM Leadership for succeeding three years from 2012-2015? The just concluded NAM 16th Summit which was successfully held in Tehran, Iran shows how Iran committed to world peace.
Since when Iran sponsored an organizations whose main purpose is to murder civilians? Since Iranian back Hezbollah liberated the illegally occupied Lebanon from Zionist IDF? And since Iran advocating the expulsion of Zionists who were landgrabbing and illegally occupying the Palestinian lands, they are now the main target of Zionists sponsored attacks through their so-called MEDIA,

.
You have to know that even if Iran is likely the victim of most terrorism happening in their country which was sponsored by the so-called freedom loving and human rights advocates of the world just like what happened to these:
Iran Chamber Society: History of Iran: Shooting Down Iran Air Flight 655 [IR655]
and this,
Partners in Crime: U.S. Complicity in the War Crimes of Saddam Hussein
Gallery of Muslim Massacres - Halabja Massacre
They did not unreasonably retaliate their enemies with an equivalent intensity of terror but intellectuallly they fought it in the UN even if they knew they will get nothing from this institution which was dominated and influenced by US of A and Israel.
Now that Iran is able to stand against their adversaries in the field of Nuclear Technology, though Iran insist it is only for civilian purposes yet Iran's adversaries insist it is for the purpose of developing Nuclear weapons. And also Iran is flexing her muscles in gaining more friends and allies by projecting their image as a real peacemaker and advocating equal social justice asides from their scientific achievements. These I think are the real source of fear for Iran's fiercest adversaries Israel and US of A.
Meanwhile, just like me, you and the for world who long for genuine peace untainted with personal interests, I like you to watch this documentary video about Iran...
