I don’t bother taking Hawaii on J1, it is only 1 ipc and slows down the necessary Jap push in Asia. A smart US player will ignore this, and the possibility of Jap strat bombing the west coast isn’t too great a concern until much later in the game (when the game should already be decided). A smart Jap player will be better off strat bombing USSR - becasue the bomber(s) will be in position to assist other endeavers such as a possible capture of Moscow. However, if I am trying for economic victory as the Axis, I will likely take it (perhaps turn 7).
