@Cpt.:
I am a huge fan of an IC in Finland as Germany turn 2. Great staging point for northern Russia assault and or increased defense of Norway as it is no longer dependent upon TT. It also alleviates the need for a Baltic navy presence, which ca greatly assist Italy in the Med. I usually plop one down in Romania as well. Capture Leningrad and Ukraine and you have capability of supporting Italy while dropping 12 units a turn on eastern front. Also creates a manageable static defensive front for Germany if the western allies start to land. Key is to keep the Luftwaffe strong (10+planes), especially bombers. Intense Bombing of London through turns 2-4 can have a devastating effect, especially if Japan is waiting for turn 3-4.
The allies won’t care if you strat bomb london since all of the fighting will be down in the Med/Middle east, they might like it since you give them free aa shots at your bombers. Landing in western europe is highly overrated. It is best that the US stays in 91 to threaten normandy/norway and to threaten a strike on italy. When Italy is convoyed out, and UK is pumping units into southern russia to contest cauc and to defend moscow, then in their spare time, the allies can start focusing on west europe (they might as well wait until the german air threat is out of range or too weak to do anything).
If Japan is waiting for a 3-4, then India will be a B-I-T-C-H, pardon my french, to take. With the likely hood of an axis pac win greatly diminished, the allies can either A, go for a full Japan contain (russia is not in any immediate danger since germany is going for the long game), or just lightly contain Japan while building up a strong atlantic fleet (have fun strat bombing canada).
