Answer:
Hitler's lightning-fast attacks on countries were known as "Blitzkrieg".
Step-by-step explanation:
Blitzkrieg, which means "lightning war" in German, was a military tactic that involved a rapid and coordinated attack using tanks, planes, and infantry. It was designed to catch the enemy off guard and quickly overwhelm their defenses, allowing for a swift victory.
This tactic was first used by the German army during their invasion of Poland in 1939, and was subsequently used in other European countries such as France, Belgium, and the Soviet Union. The success of the Blitzkrieg tactic helped Germany to conquer much of Europe in a relatively short period of time.
However, the use of this tactic also led to widespread destruction and loss of life, both among military forces and civilian populations. The devastating effects of Blitzkrieg and the atrocities committed by Nazi Germany during World War II, including the Holocaust, continue to be felt today.
