There never was any "worst", not for a long time and never really was. The whole shebang was a bandit cadre who got incredibly lucky (mainly in running into outstanding incompetence) which was then trumped up to justify spending bilions and billions more on "defense" and warfare that is not only ineffective but actually harmful to our real intentions.
Please give a link where ANY credible analyst (and no, I don't include Beck, Rush, O'loofah or any of their ilk, I want someone with journalistic/diplomatic CREDENTIALS ok??) says anything resembling what you are saying about the Arab Spring. We, of course, are already starting to CAUSE such a reaction, in Libya, but I've heard no one say that's where it comes from. The Muslim Brotherhood are considered "radicals" by their own (some former, some struggling) governments because they want things like Freedom, Democracy, fair elections, and no dictators within a muslim framework and even in getting them they renounced using violence a long time ago.
And your answer to Pakistan's problems is to leave our ally in getting OBL in the lurch because they didn't realize the well-disguised and connected businessman who, for all we know, was living in Podunk NJ all this time and just went back there to get some Allah statuettes he forgotten, was actually the most feared mastermind in the world and worth 25 mill to anyone who saw thru his deception. Yeh, let's take all our money and support away from Pakistan now, that will really hurt what remains of al-Qaeda.
