What does the term "indissoluble federation" refer to?

The term "indissoluble federation" refers to a federation that is unable to be destroyed or broken. This concept underscores the idea that once a federation is established, it is designed to endure and maintain its unity, even in challenging circumstances. It signifies a strong commitment among the member states or entities that make up the federation, intending for them to remain united over time, regardless of political, social, or economic pressures.

In contrast, other options suggest varying degrees of separability or impermanence, which do not align with the definition of "indissoluble." For instance, a federation that can be easily dissolved or one that is temporary directly contradicts the fundamental nature of being indissoluble, as they imply that there is a pathway to separation or dissolution. Similarly, a federation that is put to a vote does not inherently speak to its enduring nature; rather, it introduces the potential for change based on majority decision, which is not consistent with the concept of indissolubility.
