Which of these countries should have permanent UNSC seats?

[Del Tachi]

NOTA.

Establish a seat for a semi-permanent veto power.  One nation serves a five year term as a veto power, but cannot serve terms consecutively.  Must be nominated by 3/5 existing veto powers and then confirmed by 2/3 of the GA.

Basically, the USA, UK, and France team up to appoint pro-NATO countries to the seat while the BRICs and other third worlds are satisfied because the seat is "elected".

SEMI-PERMANENT ELECTED VETO POWER.

Five year terms.  Non-consecutive.  Nominated by 3/5 of current permanent members.  2/3 vote for confirmation in the GA.   

This was my proposal to reform the UNSC at one of my high school mock UNSCs.  I was Germany.
