Interesting. I cannot find one news article, or Google result showing Italy supporting Putin. I did see an article last week (can't find it now) in which italy was 68% opposed to Putin's invasion of Ukraine. With a high percentage undecided because Italy relies so much on Russian exports.
And in the UN, no support for Putin from Italy at all
Russia’s friends in the UN counted on the fingers
It also seems several russian oligarchs luxury yachts birthed in Italian ports have been impounded by the Guardia di Finanza.
69% of Italians want to deal with Putin diplomatically.

Please provide me with Italian media that substantiates your claim.
