You're a much more experienced player than I am, so take my advice with a grain (or heaping tablespoon) of salt.
It looks like you're committing to an aggressive forward defense (Adak, Port Blair, Rangoon). That's all well and good, but at this point in the game, Mr. Kane can take almost any hex he wants. You can make it costly for him, but if he sets his sights on Rangoon or Port Blair or Adak, there is very little you can do to actually keep the hex in Allied control. While you commit your forces forward, be sure not to neglect your secondary lines.
Plan to keep Rangoon, but also plan to lose it, and ensure that your Akyab-Imphal line sees some attention.
Plan to keep Port Blair, but also plan to lose it, and ensure that you're not leaving Columbo undefended.
Plan to keep Adak, but also plan to lose it, and ensure that the rest of Alaska is not neglected.
I think that as the allies it is easy to draw a line on the map and say "This is where I'll make my stand" in 1941 and early 1942, but in reality, where you make your stand as the allies has more to do with where the Japanese player becomes overextended once the amphibious bonus runs out rather than where the allies decide to build up.
As I said, you are twice the player I'll ever be, so please don't change your strategy on my account. I'm excited to see how the game progresses.
Please. Say that in four game months when China will be crumbling, Burma destroyed, India invaded and Mr Kane is close to an AV.
The way I see it, there is always going to be a rear area that will be vulnerable to Japan wherever I make my stand, so I chose a forward defense and hope that at least one theater succeeds.
