Each such attack adds more fuel and considering the amount of votes right wing parties get recently we sure will have a clean Europe soon.
That is extremely naive.
An uprising of right wing nationalists is not going to solve anything. Quite the opposite, it will just make matters worse.
You don't fight hate and intolerance with even more hate and intolerance.
In fact, every extra right wing vote is just fuel for jihadi recruitement propaganda.
ISIS would love nothing more then the west getting completely paranoid and refusing refugees, closing borders and booting up "security checks" based on racial / religious profiling.
That is
exactly what such attacks attempt to trigger. ISIS (and alike) have no delusions that they are going to "conquer" the west by carrying out such an attack every couple months. As far as a "war against the west" goes, such attacks almost zero effect.
Sure, there is some panic today and some economic damage. But let's look at this objectively for a second... Last count, there are 34 deaths. In Paris, there were 130.
The fact is that in a single day, more people die in trafic. In the great scheme of things, these attacks are really nothing but "inconveniences" on a state / society level.
A couple weeks from now, the damages will be repaired and life will go on as usual.
Such attacks don't even make a dent in our infrastructures.
Let's look at the biggest terror attack in the west ever by such jihadi's: 9/11.
+3000 deaths. 2 world famous sky scrapers collapsed.
Honestly, what effect did this
truelly have on the US as a nation?
Did this cripple the country somehow? Was it ever even remotely in existential danger?
Clearly, such attacks have
other goals. In a very real sense, these attacks are not really directed at people or nations. They are directed at young generations of muslim kids with an identity crisis. The goal is not to cripple nations (because they can't do that; they do not have the means or resources to do that). The goal is to divide the world into camps. "The west" versus "islam".
