Overview
- The vice president told UnHerd that demographic and political shifts in France and the United Kingdom could let figures "close to Islamism" gain significant influence within roughly 15 years.
- He warned that if European societies embrace "very destructive moral ideas," nuclear weapons could fall to people able to cause "very, very grave" harm to the United States.
- Vance presented the warning as part of a push for European "revitalization" and greater autonomy, saying a moral conversation with Europe touches U.S. national‑security interests.
- French coverage highlights the remarks as reinforcing a harder U.S. line toward Europe, citing a 15% tariff deal and travel bans such as the one on Thierry Breton.
- Reports note that his interview singled out allied arsenals while overlooking other nuclear powers, and that no new U.S. policy on allied nuclear control has been announced.
