I'm afraid that we will see a lot terrorists attacks before this madness end.
The reality of facts is, that cardiovascular disease, obesity and cancer produce much more deaths in EU, than this US created jihadist group.
This alert is directed to spend public money on useless and dangerous NATO actvity, this is only for make people to scary.
The actual state of things in EU is the direct result of EU and NATO activity in Northern Africa, Irak and Syria.
"The madness" will never End.
Study the Sharia Law, and You will stay in safety, if You will see some muslim.
You need only to have the idea, that jihadists are "salafi sect" and not muslims, they are against the words of Quran.
Pay attention to not eat dangerous food with sugar, with high glycemic index and animal fat, not conduct the sedentary life.
This is what You must fight everyday, and not other things.
