There have already been jihad terrorists among the refugees (including two of the Paris jihad mass murderers in November 2015), and the Islamic State has threatened to send jihadis to Europe among the refugees. So on the face of it, it would appear that “our greatest security against hateful acts of terrorism” would be to keep the refugees out. Counterintuitively, the Pope says that “our greatest security against hateful acts of terrorism” is to bring the refugees in. Does he have a way to distinguish jihadis from peaceful refugees? He does not. He would just apparently rather see Europeans die in jihad massacres than do anything that would disturb his sense of his own moral rectitude.
“Pope: welcoming refugees helps keeps us safe from terrorism,” Associated Press, September 17, 2016 (thanks to W.):
Pope Francis has encouraged Europeans to welcome refugees, calling authentic hospitality “our greatest security against hateful acts of terrorism.”…
The pope said: “I encourage you to welcome refugees into your homes and communities, so that their first experience of Europe is not the traumatic experience of sleeping cold on the streets, but one of warm welcome.”…
He said each refugee “has a name, a face and a story, as well as an inalienable right to live in peace and to aspire to a better future” for their children.
