Why? Why do this to yourself, Italy? Those people have no business whatsoever being in your country. They turned their countries into shitholes, so now they're moving on like locusts. You need to defend what your culture built for you, and send these people back to the shitholes their culture built for them, otherwise their culture will turn your lands into a shithole and then what?

Round these people up, whichever ones are there illegally you put them on boats and send them back across the Mediterranean. Then deploy your navy and defend your national waters with force if necessary.
