As the war is already 2.5 years old therefore, a chronology.
In 1939, Poland and Denmark both were hoovered up easily by the Axis. The USSR conquered Persia.
In 1940, France was attacked in January as everything was going well for Germany and the weather was very good. France folded quicker than superman doing the laundry with a breakthrough right in the centre of the front. Germany didn't even have to use a single o-chit. Yugoslavia was then conquered. Hungary and Romania aligned. the USSR claimed Bessarabia and challenged the Finns in late 1940 with most of their army/airforce concentrated around Finland, both claims were unchallenged.
Japan was doing okay against China at this point but nothing special. The CW busied itself trying to deal with Italy as Italy invaded Greece.
1941, Italy conquers Greece, there's a fair bit of fighting with the CW. The italian fleet is intact while the CW suffered losses, Prince of Wales included. A U-boat campaign stretches the Royal Navy super thin, so for now the Med has an Italian advantage, and the CW isn't in a very good position, though the Eastern Med at least remains under RN comamnd mostly which means the North Africa campaign goes well, but two attempted invasions of Sardinia go very badly indeed, costing the CW a number of units and some TRS. Germany invades the USSR, but the weather is absolutely terrible unlike in 1940 and progress is fairly slow.
The war in China is starting to go badly for Japan, most of the US options involve embargoes and the like and the Red Chinese especially do a pretty good job. Near the end of '41 is the oil embargo and Japan's economy near collapses, they declare war on the CW and try and snag Palembang but attempt #1 ends in disaster because I'm a noob at amphibious operations and they tried landing in the city area and got hosed by the notional unit despite all the support in the world. Lucky they have a synth oil online or it'd be over at that point but they scrape up attempt #2 and manage to get some Dutch East Indies oil. While they are being noobs CW cruisers raid their convoys and inflict heavy damage, but then the oil si back, the Kido Butai is refuelled, the CW chased away (for now) and oil secured, but while this is going on the Chinese are kicking their ar5e on the land so their position is still very bad.
1942, the Germans get as far as the Dnieper in terrible weather. The USSR suffers heavy loss, but they got a LOT of infantry due to reinforce soon - though the German army is pretty big too, the Luftwaffe is twice the size of the Red airforce, and the Germans still have two unused O-chits. The US declares war on Germany, mainly because the U-boats are slaughtering CW convoys and the CW really, REALLY needs the help at sea. The CW economy is so drained they dont have a single strategic bomber, and their losses in the Med and convoy disruptions have meant their armed forces havn't really kept up with the others.
Japan is still not at war with the US but the US has been at war with Germany for a while and so the US is getting dug in across the Pacific - not good for Japan...
Here's the UK area at the moment, Allied impulse 1 of Mar/Apr 1942. :-
