What new technology and strategy of war made hitlers invasion of poland so successful

Blitzkrieg, (German: “lightning war”) military tactic calculated to create psychological shock and resultant disorganization in enemy forces through the employment of surprise, speed, and superiority in matériel or firepower. Blitzkrieg is most commonly associated with Nazi Germany during World War II even though numerous combatants used its techniques in that war. Its origins, however, can be traced to the 19th century, and elements of blitzkrieg have been used in present-day conflicts.

The writing credits to Hurt belong to Trent Reznor of Nine Inch Nails; the song was first introduced to the world in 1994 on the album The Downward Spiral. NIN's version is heavy, and takes you to drug induced haze. It is a man desperate, lost in the world of drugs – stuck reliving his hurts with an addiction.
