A curious question I have...
If International waters are like 12 miles off the coast, then what is the problem if a russian sub is 200 miles off the coast?
Granted, seeing a Russian aircraft carrier and all, 13 miles off the coast would be considered “hostile”? Is there a buffer zone, or courteous zone, so that folks don’t get into a dangerous game?
I think there is also a 200 mile exclusion zone but its primarily for economic reasons like keeping foreign fishing vessels out.
