Youthful idealism took a big hit in lives. Live and let live doesnt work with murderous islamic savages.
The photos of the dead look to be largely young people.
This is a form of guerrilla theater, underlined in blood. But it is still theater. The actual casualties are less than a mosquito bite on an elephant's ass in a city so vast.

Any material hurt to France or Paris is purely illusory. For that, the terrorists would need nuclear weapons, or worse.
