A focus of the summit will be strengthening the defense industry through a "defense industrial revolution," backed by billions of USD in new contracts to expand Europe's weapons production. Ukraine will be high on the agenda as European NATO members and Canada are expected to pledge 80 billion USD in military aid for 2026 and 2027.

Leaders are expected to reaffirm NATO's collective defense commitment under Article 5, although analysts say its credibility will depend on genuine unity among allies.
