Willingness to manufacture is also a resource

Most countries shied away from nuclear energy production for far too long, and the tide is only barely beginning to shift back in a good direction. France is leading the way in this department, not just by ramping up nuclear energy production but also by exporting the resulting energy to less willing european nations

Also, although France does not currently mine for uranium on its mainland, there are significant deposits of it in France so your sarcastic quip about uranium growing in Macron's garden is pretty much accurate. source
