The risk in France is for the battle to happen on its land. There is a lot of racism and there is also a lot of e.g. Algerian people burning the French flag here and a lot of resentment. There are most well-integrated and well-considered Muslim people here, but there is also a minority we've completely lost. Each year the FN (extremist party) has more votes and after 2 terrorist attacks, it is a real possibility that they get elected for President 2017. From there, police arrests (of actually guilty people, but focused on a minority) can become routine, counter protests will be routine too, protest squashing will be routine, and the uproar can be as fast as a few days after the election.
