Islam hijacked Iran, as it has "hijacked" the mid-east since it's invention by Muhammad. The Mullah mafia are merely the administration and enforcers of this totalitarian philosophy disguised as a 'religion' (in fact it's religion, government and, law all rolled up as one) just as the Mullah's, Clerics and Shiekhs are the current administrators in other Islamic countries. They are merely following the Koran and ways of Muhammad, and forcing it on the masses, oppressing them. (gaining extreme wealth in the process) They haven't hijacked Islam. It's an effective war manual and cult.
Sadly, I suggest the marchers sprint, not walk.
Time is running VERY short for a peaceful solution. I suspect the Iranians would use what they perceive as Israeli-US preps to attack their sites as a legitimate reason to pre-empt. What it would serve them is....nothing.
Praying that cooler heads prevail and that there are no nuclear exchanges in the Middle East this summer.
