Nationalism isn't much praised, here, anymore (since 1919).
And frankly, I think it's best like that. It opens our country to the world, makes us think rationally. and allows for freedom of expression (when i see what patriotism does to freedom of expression in the US....).
And about radical islamism entering europe, there are three remparts agaisnt this:1) the moderate muslims who are as much victim of these currents as the other citizens;2) if it gets worse, there are ways to deal by creating muslim associations in order to have a dialogue between the state and the muslim represnetatives so that they understand our laws.
3) Anyway, if the radicals disturb the order, it becomes a police matter.
