Ok how the heck do you take USA in axis and allies Europe?  Is this some kind of inside joke?

take out the supply lines to the convoys first
then relentlessly bomb and invade it while buying anti aircraft and battleships and fighters to defend your own turf
basically take out the us before they can get motivated, i mean they get like 20 things,you could and should use your 12 beginning ipc for 1 fighter, then do the above, took out us on my second turn.

interesting
how would we be playing
im assuming this is theoretical
also i am a beginner(only started playing last week)
so new strategies and hints are welcome
also i only play europe

ANYBODY GOT SOME GOOD STRATEGIES
OTHER THAN A FOUR MOVE CHECKMATE

ALRIGHT
STRENGTHEN ONE SIDE WITH THE MAJORITY OF YOUR LARGER PIECES, OTHER SIDE=MINEFIELD(SMALL) 10 IN CORNER SURROUND BY 2 BOMBS, OPPOSITE SIDE=FLAG SURROUNDED BY 2 BOMBS.
EVERYTIME A PLAYERS PIECE COMES IN, JUMP IT WITH SO MANY LARGE PIECES(RETREAT IF THE INVADER IS BIGGER OF COURSE)
BASICALLY FAKE THE FLAG WITH A HUGE PIECE
ALSO

IF PLAYING THE STAR WARS VERSION, TRY DESTROYING THE DROIDS(THIS IS THE ONE I PERSONALLY PLAY, THEREFORE I DO NOT KNOW IF MY ASSUMPTIONS ARE TRUE), BUT THE STRATEGY WORKS EVERY TIME FOR ME

WW2 SHOOTER THAT REALLY GOES INTO TEAMWORK

it is possible, the problem is that the British player may see the action and help defend the us
