Maybe if we hadn't been so one-sided in our support of the country that stole our nukes, murdered our servicemen and maintain the largest spy operation in our country, there would not be so much blowback ill will, terrorism and radical Islamists? Plus, our support of despotic repressive dictators has not panned out so well has it - either in the Mid-east as has been the case with Mubarak and before him Saddam and before him the Shah of Iran, etc - and the rest of the world?
Though the radical elements of Islam enjoy about 25% support, most of the people there are tired of the repression and poverty and want more freedom and less pilfering of their wealth by the despots.
