@YoMomz greenland is mostly about the northern trading paths that russia has been focussing on for quite some time now. by taking greenland, usa could impose chokepoints on those routes and impose control or cause endless problems.

@YoMomz personally i am still surprised china and russia has not been developing rail all over the whole eurasian continent. much faster and way more economic than using ships to move cargo. sure, china is working on the new silk road but i think much more could be done here if all eurasian nations would actively chip in.
