What kind of extreme ideology has been spread by Iran?
It is a question of perception.. as we all know the Iranian revolution of 1979 came as a salvation for
the majority of oppressed Iranians by the Shah regime.. Now that Shia'a minorities are trying to get their rights all over the place in the Arab and Muslim world, while we never heard of oppression of Shi'a Muslims in those countries ever before..a problem has arisen!
So what is going on? A
minority trying to do a revolution? That has never worked, and only caused some troubles to otherwise stable nations..
Now, and since this started to happen, fingers are pointing to Iran as an exporter of its revolution.. but in my humble opinion, Iran is not that stupid to try to export a revolution that fitted a majority population to fit it to minority populations..
So the problem must be stirred from elsewhere playing with the Iranian revolution card to create sectarianism in the Muslim world and hence divide it, put it through military conflicts to weaken it and spread fear to sell weapons and "virtual protection".. (case 1)
With this said, if Iran or some Arab states have a hand in this, that means they are playing a political game that makes some sense to them to advance their economic, political and strategic interests on each other's back, while the populations of the region are kept haggard and anxious.. only the outcome will justify these means, and hopefully it will have a positive outcome for the whole region one day.. if this is the case.. (case 2)
