Assuming that germany is in gib on G2, if Japan declares turn 2, then at most, he has 6 loaded transports with 6 planes in range of the west coast. US drops 10 units in West US and lands some air. Not counting the potential blocking he could do. UK moves the canadians down, and/or US can block germany or just super stack east coast. Either way, they have no turn 3 attack on the US, So that is another round of big unit stackage. Turn 4 will have italy clear blockers but the US will stilll have a large defense ready.
Turn 3 Declare would mean that US still blocks a japan and so then the income for the turn can be focused on the east coast. If the US can at least delay to turn 5, then the axis have lost their only real window.
ofcourse having those transports in the Baltic makes for a great way to dump troops into Lenningrad if you opt for Barbarossa instead. Make sure you protect those transports near airbases that way you can scramble as well. I like to have 5 transports just outside of Lenningrad and 5 in SZ 113. That gives you 10 new units to drop into Lenningrad plus what you build there.
I once got a Sealion of opportunity that way. I bought a carrier and 2 transports G1. UK 1 fighter and 6 infantry for London, plus my subs in SZ 106 failed so he brought over that DD and transport with 1 infantry and 1 tank. I decided that Sealion was a “no-go”. On G2, I bought 2 more transports along with some planes, ships and land units. On G3 I attacked Russia and used those 5 transports to hit Leningrad. All was successful and I was making good gains against the Russians.
UK saw this and got a little careless. He didn’t buy any more for London and used up his stack of men in invasions of Normandy, Holland and Norway. All were successful, but I also took them all back. I had to use those 5 transports to take Norway back with men and artillery/tanks from W Germany. My Baltic fleet plus planes also sank his transports and their escorts in SZ 112. This was round 7 when I took Norway back.
The US was mostly occupied with Japan so they weren’t doing much in the Atlantic, mostly bombing my factories and building an invasion force to hit Italy, but it was still in E USA at this time. This was when the UK made a fatal error. Instead of dumping a stack of men to protect London, they replaced the lost transports and a couple of warships for escorts. London was relatively lightly defended, mostly with tanks and men to go on the transports. So, on G8 I loaded my 5 transports and hit London and took it, which also got rid of the US bomber threat.
A couple of rounds later, the US did manage to get over there and liberate London and even sank my fleet, but Italy had gotten to Cairo and I took Moscow by that time. Next round I took Stalingrad and we had an Axis win on the Europe board.
it is right below this topic (3 spaces down or something). USA economy just goes up by 23 a round sooner (but he lost dd and sub to kill nothing and that has to get reinvested, also the fighter but that kills a couple inf on average, he has to reinvest something into the pacific or he can just let japan win).
Anyway Japan in J1 DOW as far as income goes, makes the same amount as not going to war, but steals borneo and kwangtung from uk pac and phil from usa. Picks up free kills.
I am more concerned about usa buying 4 bombers, moving fighter to iceland, uk1 inf and minor complex on egypt, knowing usa will guard him in the event of sea lion g3… germany can always do a g4 takeover of london if you really want to take london. Usually germany goes barb anyway.
