What was japan's primary goal in taking part of ww2?

ok, but what is your question? as soon as you tell me i will answer your question : )

the hyksos invasion. the hyksos were able to attack egypt successfully because of their skills in using bronze weapons, composite bows and the use of the horse and chariot during the invasion. although the egyptians depict a barbarian-type overthrow, the truth is the seizure was likely a relatively peaceful one.
