Although the current membership of the Five Eyes, Nine Eyes, and Fourteen Eyes alliances is well-established, it is always possible that these alliances could be expanded to include more countries in the future. Expanding these alliances would depend on various factors, such as the potential member country's commitment to intelligence cooperation, shared values and goals, and the existing members' approval. However, any expansion would need to be carefully considered to maintain the trust, effectiveness, and security of the alliances.
