Whatever they may be called - Al Qaeda, Taliban, or the Muslim Brotherhood, among many other names, it's all about spreading Islam around the world, and there is no doubt the Islamists are winning.
They are in the process of talking over Mali (where the French have just attacked) as well as other parts of Africa. They have a lock on the Middle East (and this President will not support Israel) and of course they continue their attacks in Asia. Europe will become more Islamic as well.
We know that the US, with the most expensive military in world history, just got beat by goat herders fighting with fertilizer and that Al Qaeda is now attacking in Iraq, which America has also abandoned and where more Americans ultimately died for nothing. In fact the Islamists even seem to be winning the propaganda wars.
The Islamists feel the future belongs to them and there is no clear evidence that they are wrong.
