I've changed my mind slightly on my earlier argument. If we change the membership of the MUN SC (not the RL UNSC as I was earlier referring to) I support the accession of the G4 nations to permament membership alongside a member of the Arab League and an African nation, although I worry about stagnation caused by the veto power, proportionality is key. I think I will take Morgsie's considerations about the 'veto' into account a lot more here; although it is a tool to retain one's influence in the UN, it is often an obstruction to democratic decision-making.
