It's not whether the Islamists will succeed. It is whether the West will fail. France has the ability to squash this uprising like a bug. But it apparently doesn't have the will.
The media is on the side of the rioting muslims, masquerading around as "young teenagers". well, yeah, they are young. Young enough to lock and load and pull the trigger, make IED/s etc... So, the media will champion their cause till the media itself is being directly targeted. Then, the truth will seep out.
