In what ways is WWII similar to WWI?

There are a number of
similarities, chief among them that they were both clashes between opposing alliances of empires
and their interests.  Also, in both conflicts, the nations involved used appeals to nationalism
and militarism in motivating their populations for war.  In Europe, both conflicts involved a
two front war for Germany, resulting in two losses for her as well, and in both wars, the United
States played the role of invincible empire and endless source of supply for the Allied war
effort.]]>
