What will turn out to be the exact backgrounds and personal stories of the attackers?
And how much will that matter? (Syrian refugee backgrounds are probably the worst case scenario, illegal “invaders” the best case scenario)
How much will this strengthen the French National Front?
What will the response be of the French government? The American government? (Don’t forget the NATO treaty obligation. And will this mean Obama has to back off in the South China Sea?)
How much will it weaken Merkel, or possibly split the alliance with CSU, or strengthen AfD?
How much does it weaken the position of Schengen?
Will concealed carry become a more popular idea in the United States?
So few answers…
