what percent? just curious
I'm not gonna pull percentages out of my ass just to jump through your hoops dude
If you look at the perpetrators of the last handful of attacks that took place in Europe, you'll notice they're either refugee-born (they simple call them native-born and leave it at that, but upon further scrutiny you learn their parents are refugees) or just straight up terrorists that infiltrated the refugee program like CIA had promised to do.
This has nothing to do with refugees being inherently terrorism-prone and everything to do with the handling of refugees once they enter a European country. Obviously not every single refugee is a terrorist but that doesn't mean the ones that are get a free pass.
