What benefit was expected from this political turmoil?
Well, one of the benefits was getting to appoint Italy’s prime minister directly. Another was being able to take direct control of five member states’ national budgets, which in all of the member countries’ cases the governments fell and were replaced with politicians willing to follow the EU’s dictates. They didn’t get all they wanted out of it (which was, ultimately, the fully-realized centralized “economic government” with an appointed president, which they are still pushing for), but they did get some rather draconian precedent that they are still building on.
