I see a bunch of symbolism over substance.
Why didn’t they go into the “No Go” Zones?
Well with these attacks the no go zones IMO will eventually be gone.
It is a matter of time, but it will be the world against about 91% of Islamic populations at some point. Most of Islamic followers believe in all the crap that causes problems. Only Muslims that are not active in their religion tend to not cause problems from what I see.
