That’s correct. If the UK and ANZAC declare war on Japan, Japan’s attacks against them do not provoke the US. As long as Japan doesn’t invade French Indochina and doesn’t declare war on the US, Japan even collects the 10 IPC NO from the US. Cha-ching!
On the Europe map, Russia cannot attack anyone before turn 4 unless that power has declared war on Russia. Unless it’s turn 4 and Germany hasn’t declared war on Russia, Russia cannot attack Finland without first being at war with Germany. Even if Finland is neutral on turn 3, Russia still can’t attack it until turn 4.
