Tbf, Italy (or rather Rome) did not take care of the Colosseum for the most part of its history. Heck, carving your name and/or a penis into it pretty much has a tradition now, and as much as I hate destruction of historical or cultural objects the Colosseum is probably one of the monuments where it hurts the least. That still doesn’t make it legally or morally right, but it’s not as bad as it could be.
