Here is a question— why is it that when the Iranians went to the streets to protest the tyranny of their Islamic theocratic government, it did not catch on with all the other Middle East countries who also have been living under tyranny? The Iranian protestors used the same methods like email, texting, flash mobs, thousands of people in the street but it went nowhere. The world looked on and did nothing. But when large numbers of people take to the streets protesting a tyrannical secular government, whether in Egypt or Tunisia, suddenly the Arab world erupts with sympathetic demonstrations and calls for taking down their own secular tyrannical governments.
Could this be a stealth version of the 1979 Iranian revolution? The Egyptian protests began with Facebook postings, anybody can put on a Facebook posting, you cannot know the motive of the original poster. It may have been someone who was simply tired of Mubarrak or it could have been a stealth Muslim Brotherhood conspirator.
I have looked carefully at the crowds in the Egyptian street looking for some obvious Muslim fanatics, but I saw few who were screaming out Allah Akbar. This movement does not, so far, have a Muslim radical look about it. But that could be part of a plan. The imams could be telling there people in the mosques “Don’t blow it, don’t give it away.” The Muslim Brotherhood may have been planning this for many months, they have members in many countries including the USA and Europe. The demonstrations in the USA were interesting, I wonder who these people are.
Iranis are not Arabs. They are Persian or Azeri (only 3% Arab). Nor are they Sunni Muslims. They are Shiites. Among other Muslim nations, only Iraq has a significant population of Shiites.
There is no sympathy extended by Arabs to Persians; not by Sunnis to Shiites.
I’ll add to the other reply you received that the difference in language has a big impact. Persians and Arabs don’t have the same TV stations, newspapers, websites, etc.
