@shadowguidex:
There is a good chance that USA would have built a destroyer and possibly more for the East Coast to deal with German subs already on their coast, as well as the stack of new subs two turns away (by USA2 they are one turn away). USA is also unlikely to send all their forces to Hawaii when Germany has subs parked off Washington DC, more subs to come, and transports on the horizon as well….remember, Germany is playing like a classic Sealion attack until G2, modified with two Subs off Washington.
If you send 2 subs after the east cost, will be at the expense of sinking the UK fleet in 106 and 110.
This also reveals your intentions to Russia, who could well attack Japan instead of pulling back from the coast…
At this point, one needs to check what the US bought, the ideal Japan purchase would be 2 subs and 2 transport, or maybe 3 subs and 1 transport.
I agree though Germany should put some pressure on the US with continous naval builds.
Will all this work you think?
