How could Italy operate Harriers under its aviation law?

How would the scenario handle the Italian restriction on naval operation of fixed-wing aircraft?

Italy would either change the law or have the air force operate aircraft from the navy's carriers once the political decision to acquire them had been made.

Italy lies outside the core Britain-Australia-Canada counterfactual. If it nevertheless chooses to operate Harriers at sea, the government can amend the restriction. Another solution is for the Italian Air Force to own or operate the aircraft from naval decks. Once leaders decide the capability is necessary, service responsibilities can be rearranged around the law. This institutional barrier is more tractable than designing and funding the aircraft or carrier itself.
