UNSC in Model UN: quick answers

How many delegates are in a UNSC committee?

The real Council has 15 members. UNSC sessions on mymun seated about 15 delegations.

Does the veto apply in Model UN?

Yes. As in the real Council, a draft resolution needs 9 of 15 votes and fails if a permanent member votes against it, while an abstention is not a veto and procedural votes cannot be vetoed.

Is the UNSC a good committee for beginners?

It is demanding: the room is small, each delegate speaks often, and one permanent member voting no defeats a draft resolution. DISEC covers similar security ground without a veto.

What topics does the UNSC debate in Model UN?

Top themes in 2,802 UNSC topics on mymun: armed conflicts (24%), terrorism and extremism (7%) and maritime and border disputes (6%). Places named most often: Israel, the Middle East, Palestine, Iran and Ukraine.
