You can find the rulebooks for both Axis & Allies Europe 1940 2E and Axis & Allies Pacific 1940 2E here at this forum.
Just to understand your question correctly:
You mention: Global Pacific 2E rules…
Do you mean Global - or Pacific ?
The rules are not the same.
At page 9 in the Axis & Allies Pacific 1940 2E I cannot find any rules indicating that USA collects 30 IPC when attacked by Japan.
At page 23 National Objectives and Bonus Income- the rules describe that (when at War) USA collects 30 IPC if the United States controls Western United States.
The US player collects these 30 IPC each round for as long as the US player controls Western United States.
Note:
The US player also collects other Bonus Income - se page 23.
The Axis & Allies Global 1940 2E rules are described from page 33 in the same rulebook.
At page 37 the National Objectives & Bonus Income are described for USA.
Also, see page 39 (Additional Rules) for rules concerning all US Industrial Complexes.
Good luck & have fun:+1:
