Starving the japanese out of oil

[hmsdreadnought]

Hello.
It is possible to win against Japan with attack (raid) the 6 bases with oil (Java to Formose). You must attack Home Islands at each turn : much boats of Japan must stay in Home Islands.
You must absolutely invade Java, Singapore, Luzon, Leyte and Borneo. But you must do that before march 1944. And the US gamer have a big problem : no enough Amphib groups ! When you invade, Japan come back with amphib and invade after you ! I use directly my amphib to receive new amphib in reinforcments.
But no always possible : when you receive 8 amphib and Japan 21... !
I prefer personnaly win with this attack but very difficult.
If US receive more amphib, it would be better.
However, you may win with attack by B-29.
I do this, but it is less pleasant.
The solution : a patch who give more amphib to US.
Submarine possibility is may be an other solution.
