My answer is NO!
It was not neccessary, but the people want it!
All the problems could have been solved, but the people stirred it up so that another war was uninevitable.
The Germans never had a need for more Lebensraum, that was A.H’s dream.
The russians never had a need of spreading communism, but Stalin felt the need for it.
The americans never wanted a war but Rosewelt thought it would be better for America to expand the outerim territorys.
Everybody else was just soaked in in this filthy war and joined a side as nation they thought would win.
Are you really hot for war?
Do you think a war today like ww2 would solve all the issues?
Is a war neccessary?
