He’ll thumb his socialist nose at Germany and inflate like crazy. France will announce the return of the franc within a year. The EU will collapse monetarily and immigration controls will go back in place across Europe. England will snicker quietly.
If that does come to pass, Hollade will have "accomplished" more for France in one year than Sarko did in 4. I can only see the collapse of the EU big brother, the return of national currency, and closing the immigration floodgates as a good thing.
