The article lists Russia as the US's "nemesis". "Competitor" or even "enemy" would have been an appropriate designation, but "nemesis" means retribution, justice, or vengeance. Exactly whom is seeking retribution against whom, and for what?
Since the birth of the nation, Russia supported the US. It supported its revolution and supported the Union during the civil war. It even sold Alaska to the US. We brokered the end of the Russo-Japanese war, and about 3.3 million Russian Jews and Poles immigrated to the US by 1917. We then started down the path of trying to support the anti-communists, which of course backfired. We allied with the Soviets during WWII, but then we quickly started the cold war and formed NATO.
Since then, the Soviet Union basically wanted to control eastern (and possibly, eventually, all?) Europe, but it didn't work out, and the nations they had absorbed along the way eventually became independent again. So now their sphere of influence is smaller, but they still have a lot of nukes, and neither of us trust each other.
I would call us "frenemies", perhaps (a bit like China). But we really don't have some big grudge against each other. We're just two dicks who want to rule the world.
