Hypotetical case:
New USA’s NO: the Enterprise. If, being at war, USA holds Hawaii, Alaska, Midway and the Aleutians, USA gets the Enterprise for free! (one time NO). But wait, it’s 24th century’s USS Enterprise, with Jean L. Picard, Data, orbital bombardments, phasers, fancy high-tech weapons and even a DVD of the series! . In game terms, 24th century’s Enterprise is a 5/5 unit that repeat rolls, has 10 hits, is inmune to aa gun fire (and all other units must roll at 1s and repeat the succesfull rolls) and counts as land, sea and air unit, all in the same basket (it’s even a submarine, a trannie and a mayor IC)! You can deploy the Enterprise at any place in Pacific board, even in enemy, neutral or impassable territories. If any turn USA doesn’t buy any boats at the Pacific board, remove the Enterprise from the game forever
Sad fact:
Even with that imaginary NO, many would still say that there is not much incentive to fight for the Pacific
