[Zhang Fei]

The bottom line was that German expansion and Japanese expansion had different goals. German expansion was aimed at gaining land while exterminating non-Aryans. Japanese expansion was aimed at the traditional imperial objectives of gaining land *and* population - they were essentially aping the Chinese empire and making up for lost time.

Nazi Germany was a unique animal. Empires traditionally aren't sectarian. The Romans added foreign gods to their pantheon and employed Romanized soldiers and administrators from conquered lands outside of the Italian peninsula as a means of knitting the empire together. The Germans decided they did not need non-Aryans in the empire and decided to kill them all.

[Eric in the Ozarks]

Both Germany and Japan were on the hunt for natural resources.
