First thing I would do is bury the bodies of the terrorists (and put in out for all to see) with pigs or pig parts in their grave. According to their silly believes this will keep them from going to paradise.
Why are western nations taking in refugees from these places? How many have gone to Saudi Arabia? Jordan? UAE? How much do those countries really contribute to the fight against these terror movements.
The borders are closed in from for the first time in 1944....seems appropriate. This is the level of evil that this belief system is....on par with Nazism and Stalin.
The pressure on every level needs to be put on these nations to handle the mess in their own backyard....partly of their own creation. No more paying the freight for all of it.
Also, if these dolts were living in France for awhile, which I am sure they were, they were supported, they worshipped. The silence of Islam, from the governments of many nations to the local mosque is telling. These guys never get ratted out or turned in. They are complicit in their silence.
