Speaking on the Greek island of Lesbos, Pope Francis said the migrants there were being used for political propaganda. He urged people to focus on the causes of migration, such as ‘forgotten wars’, instead of punishing those suffering from their effects. He criticised building walls to keep people out. Saying that there are people persisting in treating the problem as something that doesn’t concern them, history teaches us ‘narrow self-interest and nationalism lead to disastrous consequences.’ The pandemic showed that major challenges must be confronted together and there were some signs of this in climate change, but little sign of such an approach to migration. He spoke in front of refugees but aimed all comments at European political leaders. His words betrayed frustration at ‘the failure of politicians to adequately address the migrant issue’.
