Well, he also devided il Sud and il Nord. But this isn't the discussion.
It's about "not everything politicians make is bad". I know that this is usually an argument made by people that sympatieyz Mussolini ("però i treni arrivavano in orario" - any far-right sympatizer), but I think that in some cases it's actually not a bad argument (for example, Giolitti and MAYBE but maybe Berlusconi).
I actually agree on this.
