Until Muslim countries become prosperous where they can accommodate their populations with adequate salary and economic opportunities, there will always be bitter Muslims who point the finger at western powers who undeniably have a hand in the destabilization of the Muslim world.
World politics and economics have a big role in shaping current and future events, no doubt.
Nonetheless, all these western Muslims can take their new way of thinking and exposure to western systems and stop contributing to the brain drain by leaving their lands, but they should go back and help change their countries.
This is not an easy task, but great nations weren't build by cowards and selfish consumerists, but by patriotic citizens and visionary leaders.
It's funny how western Muslims muster up the balls to go out on the street and riot, some breaking laws and committing crimes, but they wouldn't dare do so in their country of origin, as their government are brutal and will terrorize their entire family tree if anyone dares to stand up against them.
But now this is changing, as you see with all this "arab spring" bull, even though it's chaotic and causing significant loss of life, at least people are finally willing to die to make their country better.
But you need more than bodies with Ak's, there must be a next step that is purely political and intellectual.
Muslim brotherhood, and the likes cannot adequately provide such a next step, so all this chaos might be for nothing.
