Still Possible for an Allie win? 1942

Im currently in a game with a three other people at school and it is currently not looking very good for me and by allie.  I’m the us and uk, and obviously my allie is the ussr.  We are currently suck in the middle of a turn(can’t play long at school) and the next move is Uk.  Germany is knocking on Moscow’s door and the ussr player just wasted all of his remaining forces last turn(not taking my advice)  and is now partially surrounded with only 4 tanks defending moscow.  Germany has italy defending france and just got about 60 ipc last turn.  Germany has a huge number of tanks(at least twenty), maybe 5 airplanes, and no navy.  It will take me two turns to be able to land forces at archangel to save moscow.  Uk has a fairly large atlantic fleet and controls sea zones around europe (not med. italy controls mediterrean with starting forces)  am currently building up forces for d day.  japan is being controlled by another player who doesn’t really understand what to do and has a largly spread out navy in the south pacific.  Uk can defend india.  Japan contols chinese coast and a has a couple ground forces in alaska.  the us has a huge naval force in pursuit of jap navy while also island hopping.  am stuck with what to do with us though.  Us fleet is position to invade japan, but ran that option through the calculater and only have a 5% chance of success.  Will take 3 turns for us to build up and arrive at japan w/ reinforcements.  once ussr falls the player will control uk(only four players so at least everyone can keep playing),and i think the ussr player will scuander the uk forces once he has contol.  Is it possible to win when allies have contol of the sea and no ussr and a wasteful uk?

uk fleet blocks italia’s fleet in med.  on atlantic side uk forces take norway w/ 1 tank
