Amen! Although I would amend that to include only nations with a constitution that ensured a limited republican form of government. That would exclude even the U.S. under our current form, whereby the majority of laws are usurped and then upheld by judicial fiat.
I think that would exclude every country on earth then! :-)
We cannot expect perfection, but at least a few ground rules, like: Respect freedom of speech, right to worship, have a system of laws, the right to own property, dont engage in torture or holding political prisoners, and have a representative Republican form of Govt (Was corected on that "Democratic" is a general term these days we use to mean Republics, as there are no nations that are direct Democracies. It's a Republic that works, not Democracy, but the latter term is "popular" with the Demos :-) )
Maybe 2 levels. The first level gets you in, make it easy enough that only the ral outlaw states get booted, like North Korea etc; the second level gives you voting rights. You need some real representative Govt. sorry, Mugabe, Saudis, Pakistan, Syria, Cuba, etc. etc.
