np.LG - Without even worrying about details, let’s back up and look at the big picture here - I am going to guEss that your Allied opponents are missing the key strategy to playing Axis and Allies: the North Atlantic convoy.
As soon as possible, the UK and the US should be dumping as many infantry as possible into Norway to help Support Karelia and Russia. Very soon in the game, this will be at least 16 Allied infantry every turn into the European Theatre! And there is almost literally nothing the Axis can do about it. This infantry support turns Russia into an almost impenetrable fortress - Karelia will never fall to a good Allied player, and the Allies help defend Russia from the West, by marching troops into and through Russia. A good US player will do everything he can to ignore Japan and the Pacific as much as possible, and get masses of troops over to Europe instead.
I know this isn’t a lot of detailed information, but trust me - it is true. For the Allied strategy I am speaking of, take a look at the essays on the following website:

The essays do a good job of descibing the Convoy strategy. Read them, learn them, then play your friends with the Allies - and watch the look of revelation on their faces!
If you play the CD game, I will be glad to meet up with you online and teach them to you in person. Just send me an email at jg2_ansbach@yahoo.com.
Have fun!
