@Caesar:
as for the Japanese, they are not allowed two sea zones within US mainland.
Which exact sea zones are Japan actually allowed/restricted?
Just count two SZ from Alaska, Western US, and Mexico.
Can the russian sub move into z126 when not at war with Germany? I thougth that if you do not control a territory attached to the sea zone you can not enter it without declaring war. Or is it because it is a sub, by the way there are no german ships in that zone when the sub moved.
There aren’t any restrictions on naval movement when not at war (except for the USA, and through straits).
Thanks for the info
