I'm increasingly of the opinion that the permanent seats are stupid and shouldn't be so: China and the USA currently still make sense, but Russia shouldn't have taken over the USSR seat when the USSR ceased to exist; likewise neither the UK nor France can really justify that position since approximately the Suez crisis, and the vacuums they left behind with the end of Empire means nobody's really representing Africa, the Middle East, nor the Indian subcontinent at that level.
I think South America is also somewhat unenthusiastic about being considered the USA's back yard in this context.
* depending on if this is shorthand for "the EU" like the article (1, France), "western Europe" (2, +UK), or "continental" (3, +Russia).
