It’s about time. Hopefully sending them home will be next.
I oddly have quite a bit of faith that Italy will survive. The Italians can start by doing what often comes natural - aggravating and frustrating the Muslims. The muslims may get frustrated and move. Italians can drive people crazy. The next step is forcefully removing them.
Italy can also selectively open their borders to ethnic Italians from Argentina, Brazil and Latin America to slowly repopulate the country. Spain could also selectively do that with Latin America.
Italy is a gorgeous country. The geography is a lot like California.
