If you're Greenland, and you want to become independent in something like an Iceland or Singapore sense, you wouldn't want to become part of the US state system. You would want to forge a relationship with the US (and plausibly Canada simultaneously) that gives you maximum advantages with minimum downside (the downside of being part of the US state system is several fold right now, including the broken US healthcare system). Greenland would draw up its own terms, use the USD reserve currency, join USMCA (new NAFTA), and proceed to ride the dollar and US economic proximity to being the Singapore (or previously Hong Kong) of the greater US economic region. It could be a fascinating go-between entity with North America and Europe.
