I see more draconian laws and social oppression of Muslims in France---which will lead to further radicalization--which will lead to more attacks---and the cycle would continue.
French here need to act smart. The enemy wants to push it into a certain direction (Ehm, National Front, ehm, isolationist policy, ehm ehm..anti-Muslim hatred and bigotry). If France moves to that direction, it gives a tactical victory to criminals for ISIS and other groups who slaughter innocent human beings in Baghdad, Raqqa, Istanbul, Lahore, Tripoli etc. etc. on regular basis---and attack cities like Nice as well from time to time.
Western intervention in some parts of Arab World has resulted in devastating tragedy for the region--and bloody consequences have spilled over in European heartlands from time to time as well.
Criminals like Tony Blair should be tried for war crimes and hung. European masses should hold their immoral leaders accountable for destroying so many innocent Iraqi children and their mother's and fathers lives and so on.
Europe should never interfere in any part of Arab World and wider Islamic World again.
Muslim countries should sit down and start to solve their mess in Syria, Iraq, Libya, and Afghanistan etc.
Only then there can be any hope of peace and trade/commerce/scientific exchange can take place on desireable levels.
