The only difficulty would be deciding if the Pacific strategy is the right one.
This would be based on how strong Germany is:
Does she threaten Cau/Moscow? If so, you might want to ensure some good Western Allied pressure (western, southern, even SZ14 pressure all over the med as Darth indicated)
If Japan plays it close to home fleet wise (to keep US honest), then again, a US pacific fleet may be sub optimal.
I think if Germanys a huge inf ball in their big 4/5 territories, then it might be best to be happy having them contained and go after Japan with the Pacific fleet… you have the time to do so (and the axis have proven it might be their soft spot)
