Does a Kamikaze attack prevent subs from being ignored?
Circumstance:
The sea of Japan is only defended by a submarine. And Japan herself is also empty. The Americans move into the zone with a carrier and a loaded transport - choosing to (ignore) the sub, to take Japan.
Japan opts to launch a kamikaze attack on this SZ against the unescorted carrier.
Does that constitute starting a naval battle? Meaning the sub can no longer be ignored? and is now “defending”?
I know that scrambling a fighter would bring the sub to bare in the battle. (and in the real case I have a fighter on Japan as well, but would prefer to save it).
