Racist hegemony in our backyard but not on the Eurasian Steppe. That sounds racist to me.
The problem is the same idiocy that Condi Rice spouted about not recognizing sphere of influence, which is sort of a law of physics. You can project a lot more power locally, more quickly, forcefully and cheaply than to a landlocked area 5000 or 10000 miles away.
Projecting our power over 5,000 miles, crossing an ocean, would face difficulties. The supply line would not go unchallenged. Missile and drone attacks would take a toll. That sort of distance complicates supporting a sufficiently large army, and such an army would require a draft. Napolean and Hitler discovered difficulties fighting a ground war against a nation with eleven time zones and twice the area of the United States.
