The non-permanent members of the United Nations Security Council (UNSC) do not have the veto power. The veto power is a special privilege granted to the five permanent members of the UNSC, namely the United States, Russia, China, France, and the United Kingdom. This power allows them to block any resolution, regardless of the level of support it receives from other member states.

Explanation:

1. Veto Power:
- The veto power is a significant authority that allows a permanent member to prevent the adoption of a resolution, even if it has the support of all other member states.
- This authority is a reflection of the great power status and historical significance of these five nations, which emerged as victors from World War II.
- The veto power was intended to ensure that these major powers would have the ability to protect their own interests and prevent any action that they deemed contrary to their national security or strategic objectives.

2. Non-Permanent Members:
- The UNSC consists of 15 members, with five permanent members and ten non-permanent members.
- The non-permanent members are elected by the General Assembly for a two-year term.
- While they have the ability to participate in the decision-making process and vote on resolutions, they do not possess the veto power.
- Non-permanent members can propose resolutions and actively engage in discussions and negotiations, but their influence is limited compared to the permanent members.

3. Election Power:
- One of the powers that non-permanent members do possess is the ability to participate in the election of the Secretary-General of the United Nations.
- The Secretary-General is the chief administrative officer of the UN and is elected every five years.
- Both permanent and non-permanent members have the opportunity to nominate candidates and vote for the Secretary-General.

4. Military Power:
- The UNSC has the authority to take military action to maintain international peace and security.
- However, the power to deploy military forces rests primarily with individual member states.
- The UNSC can authorize the use of force through resolutions, but it is up to member states to provide the necessary military capabilities.

5. Judiciary Power:
- The UNSC does not possess direct judiciary power.
- However, it can refer cases to the International Criminal Court (ICC) for prosecution when it comes to crimes against humanity, war crimes, and genocide.
- The ICC is an independent judicial institution that operates separately from the UNSC.

In summary, the non-permanent members of the UNSC do not have the veto power, which is exclusively held by the five permanent members. While they have significant roles and responsibilities, including participating in the decision-making process and voting on resolutions, their influence is limited in comparison to the permanent members.
