Yes, for the most of the people fleeing that was the sum total of their involvement. And for a small percentage of those people they either are taking the fight with them or have other plans. It's a tough situation, on the one hand no right thinking person has a problem with sheltering refugees, on the other hand those very same people are worried about what the long term consequences of these mass movements of people will be. One thing is fairly certain, the Schengen agreement (which has done more for the unification of Europe than almost any other EU activity short of the launch of the Euro) is going to be a casualty.
It is already changing. Give it a few weeks. Sweden and Hungary have already put border controls back in place, France will likely do as well as a result of this attack at least for the foreseeable future. After that - and coupled with the immense increase of cross-border crime in the last decade - it will be a fairly easy step to rescind Schengen, if not in name then at least in spirit or on a 'temporary' basis. It's the easiest way out of a lot of the current problems and it is a lot cheaper than militarizing the Balkans which has other side-effects that are mostly undesirable.
Border controls are one thing. Freedom of movements is another. Being forced to flash id card at the border is not the same as the border officer being able to refuse entry to a legal EU citizen.
