Playing as Japan, I attacked the American Navy on the west coast of the U.S. and occupied the two sea zones that connect with Western United States. On their next turn, can the U.S. put ships in either of those sea zones?
Common sense would tell me the answer is no, but the rules confused me. They say "New sea units can enter play even in a hostile sea zone. (No combat occurs because the conduct combat phase is over.)
It's written pretty clearly, but doesn't make sense to me.
