D-day

[Mikeus Caesar]

As well as all the other reasons stated here, it also prevented Uncle Stalin from rolling through Germany and into the rest of Western Europe.

d-day was important, becuz it would divert the attention of hitler. it now had to great treats to watch out for. it was also imrtant to free as much of europe before the russians did. cuz everybody knew that once they'd conquered it they sure werent going to hand it back as america did. Russia was a worthy ally for both sides, but even more a dangerous communist threat.

if d-day wouldnt have taken place, the war would have taken much longer. i dont believe germany would have won. but whe were going to be in syberian death camps.
after berlin had fallen hitler would have evecuated or commited suicide, but russian wouldnt have stopped fighting. maybe steamroling over switzerland as well.

if D-day would have failed but did took place, it would have been even more catastropheus (sp?). it would boost the german morale and maybe crack that of stalin, wich i highly doubt. but atleast england wouldnt have been a threat anymore, and he would underestimate america.
