This is off subject but has to do with the fact of the U.S. building a minor IC in korea. Can they move within striking distence of that when there not at war even though Japan can not end movement withing 2 zones of alaska or the western U.S.?
Yes. The United States is only prohibited from being next to Japanese soil in the Pacific. If they want to leave their fleet next to SZ 6, but not in SZ 6, they may do so.
