France’s relationship with NATO is under fresh strain as disagreements with Washington deepen over Greenland and European security. A senior French lawmaker openly questioned staying in the U.S.-led alliance, arguing NATO risks dragging Paris into conflicts that undermine national interests. The debate comes as President Emmanuel Macron pushes for greater European strategic autonomy following Russia’s use of the nuclear-capable Oreshnik missile in Ukraine. Tensions intensified after Trump remained firm on his push to acquire Greenland, prompting France and other European states to deploy troops under Denmark’s Operation Arctic Endurance. The move signals Europe’s willingness to act independently as trust in collective security frays.
