That was almost 10 years ago. That does not an existential threat make.
There have been a number of similar attacks in Germany since. There are no signs of this stopping.
Noone claimed it was an existential threat.
The interesting thing is that the laws being created to protect against such extreme attacks will be used against the people when they are controlled by an extreme group.
Then why do they put Merkel's lego (concrete blocks) at every winter market now?
