Obviously we are not doing well with Italy. Normally she stuggles. She can do fine shortly but is normally shut down by the UK.
Germany is often doing good so to get Itlay going seems key. In Global japan si sledom weak either so Italy is the missing Axis link for us.
Persia is four (4) steps from Moscow for a plane, the Caspian sea is flyable. Persia -Caspian Sea-Kazahkstan-Samara-Moscow. By UK4 the first plane built in Persia are in Moscow. But also UK4 tanks and mech plus the Persian free inf could be in Caucasus. UK planes in Moscow can fly out to support a British attack and then land back in Moscow.
Germany has the forces to march to Moscow but an attack G5 is not assured to be at good odds.
If you loose the attack badly it’s game over. If you are strong next to Mocow G5 and the Russians not great!
Our issue is that if you cant take Moscow fast the allies build/reinforce a lot so Germany has to do serious production nearby (Ukraine/Novogrod even Volgogrod and/or Romiania) to outbuild them. That takes time = USA lands in the West.
I like the suggested German bomber strategy, can see how it stops the Russian building 10 infantry in Moscow (or forces them to pay a lot extra to build many units). Will try that next time. This could crack the pesky Southen help from UK or Iraq… untouchabale income issue
