Short note on how a clash with NATO could affect the USD

Short-term: USD usually strengthens sharply as a safe-haven currency during sudden geopolitical crises (investors rush to dollars & US Treasuries).

Medium/Long-term: A serious clash (especially if it fractures NATO or involves direct US-NATO conflict) could seriously weaken the USD over time by:

Accelerating de-dollarization (allies & others reduce USD reserves & trade reliance)

Triggering sales of US Treasuries by angry or fearful allies

Raising US borrowing costs and inflation

Damaging global confidence in the US as the world's reliable financial anchor

In summary: Initial boost → potential long-term damage to USD dominance if the clash is severe and lasting.
