Again, Russia would need to fight harsh natural disasters first. If any, they will need us. Earthquakes due to ice melts and current flows will be no joke. Temperatures will be warmer in the Arctic, and a potential small war due to gas/resources/routes will happen, everyone knows that. But what no one speaks it's that the damn nature can crush any vehicle in between no matter if it's from USA, Europe, Russia or China. It will be scary and nature doesn't give a shit where are you from. Every base you set on either ice or the coast can be plummeted down due to a quake/tsunami in hours.

Also, back to economics. The inner European market can be huge. We have decent armies ourservers, too, among market with the whole Mediterranean, Africa and South America (Spaniards know how to do deals, no matter which political side). Oh, and don't forget China, the Chinese will love to sell us advanced tech at bargain price.

The US tries to set right wing sided mafias in LatAm, Europe tries to get good deals. The US needs to behave like gentlemen and not like thugs.
