NATO faces credibility crisis amid US and French political shifts

NATO faces simultaneous pressure from both its primary pillar and its primary threat. While Russia remains the external threat, the United States, traditionally the alliance's pillar, is increasingly viewed as a potential source of instability, creating a crisis of credibility for the treaty's guarantees.

In France, political movements are pushing for a withdrawal from NATO's integrated command. The France Insoumise parliamentary group filed a resolution in January 2026 to initiate this process, and Marine Le Pen has stated she would withdraw from the command if elected in 2027. Unlike the complex legal hurdles for a potential American exit, the French path follows a historical precedent from 1966, making it a more accessible political option.
