Actually terrorism could actually be targeted against the EU.
It&#x27;s really hard to say if there wouldn&#x27;t be any without the EU. But I really think that without opening the borders as it was done with some EU contract, it wouldn&#x27;t be as worse at it is now. If these days somebody would bomb some citizens it&#x27;s really hard to say from where these people would come. In most parts of the EU you could&#x27;ve just go in and out whenever you want without many controls. 
It changed lately but still a lot of people are here now which could be good or bad, we don&#x27;t know, we actually don&#x27;t know anything about them and they don&#x27;t know anything about us. 
This could lead to terrorism as well. I mean if some groups can&#x27;t correlate with other groups that will be troublesome.
Hopefully everything goes well.
