It certainly makes no sense the the US to store nukes in Turkey if it cannot fly them out.
I always thought that the main point was that the US cannot win a land war in Asia, as the Chinese have many, many more troops than the US could ever have. The only way to defeat the would be with nukes. I do not think that the Chinese are any serious threat to the US. They want to sell us stuff. We have bankrolled the fastest modernization in human history: highways, auto factories, electric plants, railways and all that were paid for from profits made by selling us shoes, clothes, electronics and all sorts of other stuff.
