iceland was never a ruling country of greenland and has not had settlers there in decades with most the ones in recent history having arrived there while iceland was part of danemark or danemark norge  iceland has neither the claims for it nor the population resources or means to hold unto it settle it or reform the systems already in place norge hasnt had it in over 200 years and even then it was as part of danish rule under danish monarchs sweden does not even deserve mention next to danemark on the matter and iceland should not be in the talks  and norge has not ruled greenland seperately from being ruled by danish monarchs since 1380 why should it be norwegian when it has been ruled by danish monarchs and settled by majorly danish people for nearly 700 years why should norge have it when they barely ruled it for any one time without danish monarchs and most the norwegian monarchs that did rule greenland separately to danemark where descended from danish monarchs with danes not representing an insignificant part of the people involved in the settling ruling and taking of greenland  greenland should not be part of norge just the same as portugal shouldnt be spanish the only acceptable scenario with norsk rule would be under a joint dansk norsk kingdom or union (where i would prefer the monarchs be separate because i like king frederik d. x and the danish royal family but i also like the norwegian royal family who are descended from the danish royal family having taken the throne back in 1912 was it ?)
