Let the negotiations begin.
I foresee a substantial US Navy Base in Greenland with suitable facilities to house and supply a US Marine expeditionary force , created to resupply US aircraft carriers and US nuclear submarines.Iceland will be on board as well.
Nuuk is about to get a YUGE airport, Aviation fuel depot, and hanger facility first.
(You never know, maybe FReeper Allegra will be workin' on it.)
NUUK:
Shortly before i arrived at my duty station in the army in 1993, a squad from the platoon i would wind up in, went to greenland for a week to blow up an outdated radar tower or something like that.
It was an officer, some civilian liason dude to coordinate with greenland govt if needed, an NCO, and 4 enlisted guys to do the work with the explosives
They had a great time because they always talked about the cool little operation as time went on. If i recall, they were able to do some hardcore fishing with the locals.
