"The Pope is not a wizard. But doubtlessly, he will remain faithful to his message," says Vilnius University historian Vytautas Ališauskas, Lithuania's former envoy to the Holy See.
"On the other hand, the Pope is definitely not proposing irresponsible acceptance of the refugees. The governments' job is to make sure they are integrated, that they find a place in the society, that they are properly informed about the society they live in.
"But it's not the Pope's job. The Pope is urging to create an atmosphere where refugees could feel dignified. We all know that where people feel dignified, there are fewer problems [with radicalization]," according to Ališauskas.
Speaking ahead of his trip to Krakow, Poland, Pope Francis said on Wednesday that the world was at war.
"The word we hear a lot is insecurity, but the real word is war," the pontiff said.
"We must not be afraid to say the truth, the world is at war because it has lost peace. When I speak of war I speak of wars over interests, money, resources, not religion. All religions want peace, it's the others who want war," Pope Francis added.
