And they're going to keep happening until France stops attacking (the terrorists) themselves, I think is what I read from statements.
I honestly, and I'm telling the truth here, don't know the exact reason the attack happened. But I do know they're taking in a lot of refugees from the countries affected by ISIS. That might be one of the reasons why they were attacked. There's a TON of talk of not allowing refugees in from mainly Syria now due to it, which will not help with the situation. One political presidential candidate is trying to lock out everyone EXCEPT Christians from entering the country. Which breaks so many constitutional laws that everyone who made the US would roll in their graves finding out. My thoughts and prayers go to the victims and their families.
Germany and Sweden are taking in a lot more refugees. It' s just marketing if you ask me. Matches their propaganda. France, being one of the most staunchly secular countries in the world (if not the most), is a perfect choice for them to put up a show. We' re not their only target (nor exactly the one with the most casualties), but they say themselves we' re their enemy number one for that reason.
@Sara, you might want to read this : http://napoleonlive.info/what-i-think/the-muslim-mind/ It is a long read, but that' s just it. I don' t think the motivations of Muslim extremists at large can be explained both concisely and satisfyingly.
