The US has less arctic capability than just the Nordics, not including the Baltic States, Germany, France, Italy and the UK who also all have arctic specialists. How is the US the best country to defend that zone? Less usable equipment, less personnel, less spec ops? Clearly not the planes, f35 can't operate 8 out of 12 months in arctic conditions, unlike the grippen (at least they won overheat). The only part where you need the US is the Navy, because it allows you to project your power, but how does it help against an invasion, where the logistics are on your side anyway? That's pure cope.
