Actually, no.
The FIRST time was the result of French foreign policy (alliance building) and a bunch of murderous left wing thugs willing to light any available fuse who did.
The second time was because of the first ending the way it did and how the already festering neo-pagan mysticism of the late 19th century took advantage of it.
The third time, if it happens, will be because of Islam and a deluded and therefore suicidal culture of European guilt for history.
The third time probably keeps growing. Merkel is being stubborn beyond reason. Sweden is on the edge an once the first shots or knives are used the fuse will be lit. Germans in the street in mass is the last place they should be in a country that has it all.
