To go along with the strengths of the global war; If the US chooses to purchase entirely in the pacific, Germany has several options. Our games J1 DOW is pretty much an inevitability, but Pearl is rarely done for the reasons above. With well coordinated attacks Japan will be making $70 per turn and more every time ($137 is my personal best).
I love to bait that big fleet close enough to my mainland planes by dancing around with the bases to the point of madness. If we are successful in baiting their large fleet into a winnable fight the pacific can be free of US capital ships. With all of the money that you have made it is an easy pivot to transport up and go into the weakly defend USA.
