Mmm really you can not abandon Island hopping, you have spent resources but you are also obtaining results. And if you are at turn 6 and Russia is still alive you may still turn the table.
I suppose that a good option is to focus on East Indies then, try to build a factory there and engage the Japanese forces, avoiding Japanese focusing on Russia.
The problem is that UK have to:
- control the Atlantic;
- liberate Africa;
- put pressure on Europe.
All this objectives may be out of reach for the british alone, so I would suggest focusing on the first two and try to stay alive with Russia, which may be the real problem in this scenario.
But, sincerely, I think that Pacific strategy with USA, though may bring to good results, is a long time strategy, maybe too long.
The problem of the Pacific Strategy is that USA is not helping directly Russia, because reduce Japanese rush to Moscow but Red Army is forced to face a stronger Germany, which may a have a more easy life against UK alone.
I prefer to go all in Atlantic with USA in the first turn, with the objective of winning the Battle of Atlantic, liberate Africa and starting to create problem in Europe.
I have no problem with the KGF and JTDM. It is only the high level objective of the game.
The important, and funny, things to do wth A&A are the logistic, the planning and the conduction of the combats.
Also Chess have only a way to win, checkmate the oppenent King, but there are numerous way for obtaining such objective!
