Kyrial, you probably have more experince than me at this game but i find this strategy works.
What I do is send the 2 British fighters to Western Canada. Then as America build an Ac plus subs. On the British turn land the fighters on the Ac.
Supposing its 1 hit bbs, then the japs should have 2 bbs, an Ac, and 1, maybe 2 fighters. So that fleet versus the Anglo-American forces of 1 bb, 1 Ac, 2 subs, 2 fighters, and a transport. If Japan was lucky they might be able to beat that fleet!
Next turn Britain flies Fighters to East Canada and America lands more fighters on Ac and builds what it sees necassary.
By crippling Japans economy i didn’t exactly mean that only, hopefully if the Brits play well they might have some of Eastern China.
Even if Germany does slaughter the allies in Africa theyre doomed once Japan has fallen.
