[edit]:
The town of Atka apparently has a population of 53, spread over 32 households. There's an airport, but some expansion would probably be needed to handle Shanghai<->Oakland shipping traffic...
I'd guess that getting fuel to an island would be much more expensive negating the benefits. (I understand that this was not a serious suggestion anyways).
I wonder why it has not been done? Maybe because of this -
"In 1996, the U.S. Department of Transportation exempted Alaska's Anchorage International Airport and Fairbanks International Airport from the Jones Act, which prohibits foreign airlines from transporting cargo between U.S. cities. Now, foreign carriers are allowed to refuel their planes in Alaska before continuing on to an American airport or returning home. Because of this, Ted Stevens Anchorage International Airport now handles approximately 80% of all air cargo traffic between Asia and North America."
Maybe you need to find a non American location. A floating refuel location?
