I tend to think of blitzkrieg as a strategic concept of using surprise and/or concentrated forces to relatively rapidly collapse the military and political resistance of an enemy nation, by deep maneuvers into the unprepared rear areas. The key concept for me is the fact that the country is to be utterly defeated by these maneuvers.

As such Poland, the Low countries, France and the Balkans are of the successful variety. The Soviet Union is the main contender for halting an attempted blitzkrieg.

I would not call Bagration (for example) a blitzkrieg as such, having a more reasonable operational success in mind rather than knocking the enemy out of the war.
