Japan never at any point felt like they could take the war to U.S. soil and hold any appreciable gains.  Had we lost Midway, Japan would have concentrated on securing their holdings in the Philippines and China.

Didnt the Japanese land on the aleutians during the war?

Yes, they did, as a divsionary tactic to make the US think that Midway was NOT the intended main target.IIRC they finally dislodged them in early 1944.

What about this one:                                  ::) ::) ::)http://www.imdb.com/title/tt0053084/

I would have to say the Tet Offensive was a turning point in history. While a US military victory, it was precieved as a loss, and public support for the war in Vietnam started to really sour. Without this "win", the North Vietnamese would have had a much longer war, if they won at all. 

Ten years ago, I worked for a gentleman who'd served 3 tours of duty in Vietnam; one during the Tet Offensive. During lunch one day, he noticed I was reading a book about the Vietnam conflict and he offered a great deal of information not covered in school nor in the book. At the end of our meal, he commented that our discussion had been one of the few times anyone had shown interest in his service in the military. Sad, in my opinion.

Hastings, Trafalgar, Gettysburg, Normandy, Stalingrad, Vicksburg, Zama, Waterloo, Valley Forge, Actium….oh I could go on and on there are so many to choose from.
