from a strategic point, securing greeland is absolute good decision for usa and trump is history leader for that (if not for the fact how he does it, i.e. bullying own allies and threats). there are 3 aspects: 1) nukes - majority of russian nukes in case of ww3 will fly through north pole, so setting up a shields in canada/greenland is only way to try to intercept them. 2) everyone contesting for arctic resources, and us kinda having bad bards there, since only countries directly bordering it has a stake. canada and denmark do, usa lags behind. plus greenland own resources being available due to global warming. 3) northern shipping routes opening up due to global warming. so what trump does is completely logical, you`d do the same if you played a game like civilization. except reality is not a game, and his clear intent to control canada and greenland by threats, is shitty approach. should have done calmly, diplomatically and silently.
