I think it's important to recognize that there's not just one European worldview and that Mr. Trump's views coincide well with those of an increasing number of Europeans, many of whom have always resented both the EU and the Mogherini-led coalition that brokered the deal with Iran. With Merkel's position considerably weakened and no appetite to keep bailing out failing economies, Mr. Trump may find more support than we would expect. So far, the press for this visit is cautiously optimistic about bringing him around to their position, but the leadership also understands it has fewer cards to play today than in years past.  We'll see what happens in Sicily.
