Remember the all-out attack on the Grand Mosque in Mecca in 1979? IIRC, it was carried out by Shias, aided by Iran. Saudi security forces took the attackers on and it was quite bloody. My family and I were prepping for a move to Jidda, (60 miles from the Mosque) and my mother and mother-in-law were quite nervous about this move.)
I used to really want to go back to Istanbul for a visit. then when I finally reached a point that I could afford it, well, it was obvious it was not the same culture as in my childhood there and I have not gone. I heard many stories of Ataturk and how it once was in the bad old days. The bad old days seem to have returned.
