Reply #6: Why would they need to launch these from Kadena

[Art_from_Ark]

way the bleep down in Okinawa, when they've got Misawa just across the pond, so to speak, and Yokota not too much farther away.

Also, I don't know what you mean by "clearing the way for a massing of troops on mainland Japan". Whose troops are you referring to? NK? No way would they try that -- it'd be too hard to hide the build-up, and the boats in their rustbucket flotilla that weren't sunk by the Japanese would probably sink on their own.
