In light of the political unrest in Bahrain and the military involvement of Saudi Arabia to assist the Sunni political establishment in the country with the majority Shiite population, the timing was right to write on the Sunni-Shiite relationship since the creation of the Islamic Republic in Iran over 32 years ago. I posted a lead on the issue here.
Unfortunately, the time has been hectic recently, both at work and study. Therefore I had to remove the lead for now. I am sorry for that. I am still interested to write the piece, however, don't set a time.
